    • Solar PanelsSolar panels/modules essentially work like a car battery charger, except instead of plugging it into the wall, you put it out directly in the sun. How do solar modules work, and why should you consider an off grid-power system? Solar Panels for Your Home – Converting Sunlight to Electricity Photo-Voltaic or solar cells convert sunlight directly to electricity within wafer thin cells. Light “particles” called photons actually bounce electrons across a barrier, creating an electrical current.  This allows you to produce solar power for home use. Read More Cells are sealed within a tough resin between a tempered glass front and plastic or foil backing, and then framed in aluminum rail. There are many sizes and brands of solar modules for off grid solar power systems, at similar prices, specifications, and claims. New brands come each year, many as good as, but none better than, the proven reliable brands listed in the next pages. Considering cost and length of solar module lifetime and warranty, we stock the longest tested and most respected brands.

    • Solar WiringWiring Individual Solar Modules Once the panels are mounted, wire must be connected from each solar module to receive the power generated. Sunlight resisitant flexible 10 or 12 gauge wires connect from each solar modules junction box to a combiner box. You will find bulk wire, as well as pre-cut wires with terminal ends or MC cables and weather tight box seals in the following listings. Diagrams for wiring for various voltages are in our Learning Center.  Read More Grounding the Array The aluminum frames of solar modules need to be grounded, either by using UL rated grounding clips, WEEBs or with a grounding lay-in-lug attached to each module and a copper wire run between the lay-in-lugs. Copper wire is most cost effectively sourced locally at your hardware or electrical store. Wire Size & Distance Much larger wire for positive, negative, (and sometimes the ground rod) run from the combiner box/s to the battery room. These run in conduit from the box to underground, and often also in conduit the full distance underground. The wires are larger, and are limited in permissible length because any voltage drop would reduce the solar charging. Arrays for 24 and especially 48 volts are allowed much…

  • WindOur wind power options are best suited for maximizing power production in the winter months, night time power production, and ideally suited for hybrid applications with Solar PV. We have several tools and books available as well for assessing your site for wind power. Read More At a good site, a wind turbine can generate more power for its cost than solar modules. Both together can give steadier input since a wind turbine charges the batteries in storms when there is no sun, and at night. But beware of erecting a wind turbine where the wind is not strong and steady. An area’s wind-speed, as well as the immediate terrain, will determine how well the wind turbine performs. If in doubt, we suggest starting with solar modules, and checking the wind for a year. This will show whether to add a wind turbine or more solar modules. Twelve to fifteen mph average year-round winds are necessary for an optimal installation, and these sites are not common. Wind turbines must mount at least 30 feet above trees and obstructions for 300 feet around. They need non-turbulent air where a weather vane holds a steady direction. Charge controls for wind turbines are…

We also carry books and DVDs to help you set up and benefit from micro hydro power. Micro-Hydro Advantages & Performance Water turbines steadily charge 12, 24, or 48 volt batteries, working 24 hours a day every day. Compare this with solar modules in sunshine for at best, 6 full-power hours a day, and that’s just on sunny days. A hydro generator producing 10 amperes around the clock matches the usable power generated by over 40 amps of solar modules. So cost is a lot lower with hydro. The power system itself is the same as solar, except only diversion type charge controls can be used with hydro. Pelton wheel generators use a small volume of water raised to high pressure by running downhill in a penstock (pipeline). Pressurized water shoots from nozzles to strike and spin a cupped wheel on an alternator. Other types of wheels and propellers handle water sites with less pressure (head) and more flow volume.

  • Charge ControllersCHOOSING A CHARGE CONTROLLER Charge controllers regulate the output of solar modules, wind generators and hydroelectric generators to prevent overcharging of the battery. For off grid solar power systems, when battery voltage rises to a preset maximum, where the battery is completely charged, the control automatically reduces or stops the solar charge. Some charge controllers are that simple, but most include some other features like volt & amp meters, voltage conversion, low battery load disconnect or night light timer. Read More VOLT AND AMPERE RATING OF THE CONTROL Select a control able to handle a little more than the amperes your solar modules are rated to generate. Though solar modules don’t usually produce more than their rated amperes, they can momentarily produce 15% more on cold bright days. The electric code recommends leaving a 25% margin, that is, for a 47 amp solar array use a 60 amp control rather than a 50 amp control. And if you plan future expansion of your solar array, allow a lot more headroom to accommodate the added solar panels. Be sure the model you choose is designed for your battery voltage: 12, 24 or 48 volts. A given control will handle twice as…
    • MPPT Charge ControllersMPPT Charge Controllers for Off Grid Living MPPT charge controllers employ DC to DC conversion, which allows the solar array voltage to be higher that the voltage required to charge the batteries. Many years ago solar modules were designed to charge 12 volt batteries. These solar modules were built with 36 cells in series to have a peak power voltage of 16- 18 volts. Two of these modules could be wired in series to charge a 24 volt battery and four could be wired in series for a 48 volt battery. Modules with 72 cells were also available for 24 volt charging. When all modules were made this way, the simple PWM charge controllers described previously worked fine. As connected off grid solar power systems became the prominent use for solar modules, cost became the most important factor in module design and off the grid homes. This lead to larger 60 cell modules, manufactured in a convenient size that could be carried by one person. These modules have a voltage too high for 12 volt battery charging and too low for 24 volt battery charging and are usually wired in series to get approximately 400 volts DC which is easy…

    • PWM Charge ControllersSERIES CHARGE CONTROLLERS – Connected between the charging source and the battery. Pulse width modulation (PWM), used in all modern charge controllers uses 3-stages of operation to give the most charging possible for the day. BULK charge is the first stage, where the maximum power available from the charging source is fed to the battery until it reaches a preset voltage. ABSORPTION is the second stage charge where the maximum battery voltage is held by reducing the charge current just enough to never exceed the target voltage. Reduced current is done by high speed on and off pulsing, where the controlling “on” time versus the “off” time of each pulse determines the average charge current. During this stage of charging there will be some bubbling, or gassing of the battery electrolyte. This is necessary to maintain the health of flooded batteries. FLOAT is a third stage where battery voltage is reduced after charge is complete. This avoids excessive evaporating of battery water and benefits battery life. When sealed, maintenance-free, AGM or gel type batteries are used, voltage set-points are lower to prevent gassing of the battery.

DC OR AC APPLIANCES: Folks with the smallest solar power systems and few; simple appliances may have no inverter, and use low voltage DC for all lights, radio, TV, and water pump. People using the largest solar power systems sometimes use AC power from an off grid inverter for everything. Usually it is most practical to use both inverter AC and some direct battery DC. AC is most practical for regular household outlets and lights, because most AC appliances are better quality, easier to find, locally available and lower priced than 12 volt DC versions. But a few special DC appliances can save a great deal of energy. Items that drain a small amount of power over long hours can use…

  • Power CentersTHE HEART OF THE SYSTEM LIES IN THE POWER ROOM Electricity flows from solar and/or wind through a charge controller and into the battery (hydro goes through a fuse or breaker directly to the battery and is regulated independently). From the battery, power goes out to any DC house circuits, and the inverter/charger producing 120/240 volts AC. The hub of the system is often a DC rated circuit panel (or a set of fuses) housing charge controller, inverter, and AC circuit breakers.

Learn more about solar batteries and battery care below. Read More Battery care is your main responsibility with homemade electricity for off grid power systems. This is the one part of your power system likely to be harmed by neglect or misuse. Lead-acid batteries, the standard in home energy, should not discharge more than 50%. Ideally, they should be recharged to 100% promptly. They can be damaged by undercharging, continued overcharging, or contamination. Do not store batteries without periodic recharging. Continual self-discharge when not in use can ruin even a brand new set of batteries. Sizing of 1000 to 2000 amp-hour 12 volt (or 1/2 that in 24 volt; 1/4 that in 48 volt) battery bank is desirable because a larger bank can accept faster charging by generator and give high power discharge for inverter surge without strain. In northern areas short on winter sunshine, more reserve before running down to the 50% level is also a benefit. Use our catalog’s 6 introductory examples as a guide to battery size, or…

      • Diversion LoadsConnected between a battery and dump load. Diversion Charge Controllers are typically used when the charging source cannot be disconnected from the battery, such as wind generators or hydroelectric chargers for off the grid electricity. Diversion controllers do not cut off current from the charging source at all. When the battery charges to the maximum set voltage, the diversion controller connects a “dump load”such as ceramic air heating resistors or water heating elements to the battery to dissipate the energy coming from the charging source. The controller adjusts its consumption rate to offset the excess charging exactly, and keep the battery voltage at, and never exceeding, the preset maximum voltage. If you use a windmill for off grid living that does not have its own charge control, or use hydroelectric generating, a diversion control must be used, since those generators can be damaged if their charge is not absorbed in the batteries at all times. One diversion control handles a combination of solar, hydro and wind, so long as the total amps charge from all of them taken together is within its amp capacity.

    • LightingLighting for Off the Grid Homes LIGHT WITH LESS POWER Photovoltaics solar panels convert just 10% of sunlight’s energy into electricity. Ordinary light bulbs convert only 10% of that electricity back into light (the rest becomes heat in the bulb). Because lighting is a major part of power used in solar homes, special high efficiency bulbs that save 75% of the power are well justified. Read More COMPACT FLUORESCENT BULBS Compact fluorescent bulbs make far less heat and more light. Using one fourth the power of ordinary bulbs, a 15 watt CF has the brightness of a 60 watt incandescent. It runs 4 times as long on the same power. They give the same soft white light and should last as long as 6 ordinary bulbs. The cost of these lamps is much less than adding extra solar modules to run low cost incandescent bulbs. Backwoods sells compact fluorescents that have electronic ballasts which are silent, have no flicker, and no PCB oil in contrast to heavier low cost magnetic ballast sold in stores.

Read More Our inverter section explains that often AC power is more practical than DC when you are using lower cost quality appliances and conventional wiring. There are important exceptions where special DC powered appliances can save lots of energy, money and/or avoid technical problems.  Special DC designs of evaporative coolers, refrigerators, water pumps, fans, bed-warmers, plus re-chargers for shavers, flashlights, and cordless tools all use much less power. AC electric blankets use 200 watts; DC bed warmers use under 60 watts and avoid questionable AC magnetic field exposure. DC fans and evaporative coolers use less power than AC fans and don’t hum. DC powered pumps use less than 25% power per gallon, pumping slowly with low wattage, and do not monopolize your inverter at unpredictable times. Advantages and disadvantages of AC and DC pumps are explained in the pump introduction pages. Some devices must be on duty 24 hours a day. Motion sensing lights, telephone message machines and cordless phones, timers, intercoms, cell phones, and smoke alarms all need a trickle…

    • Solar WiringWiring Individual Solar Modules Once the panels are mounted, wire must be connected from each solar module to receive the power generated. Sunlight resisitant flexible 10 or 12 gauge wires connect from each solar modules junction box to a combiner box. You will find bulk wire, as well as pre-cut wires with terminal ends or MC cables and weather tight box seals in the following listings. Diagrams for wiring for various voltages are in our Learning Center.  Read More Grounding the Array The aluminum frames of solar modules need to be grounded, either by using UL rated grounding clips, WEEBs or with a grounding lay-in-lug attached to each module and a copper wire run between the lay-in-lugs. Copper wire is most cost effectively sourced locally at your hardware or electrical store. Wire Size & Distance Much larger wire for positive, negative, (and sometimes the ground rod) run from the combiner box/s to the battery room. These run in conduit from the box to underground, and often also in conduit the full distance underground. The wires are larger, and are limited in permissible length because any voltage drop would reduce the solar charging. Arrays for 24 and especially 48 volts are allowed much…

  • WindOur wind power options are best suited for maximizing power production in the winter months, night time power production, and ideally suited for hybrid applications with Solar PV. We have several tools and books available as well for assessing your site for wind power. Read More At a good site, a wind turbine can generate more power for its cost than solar modules. Both together can give steadier input since a wind turbine charges the batteries in storms when there is no sun, and at night. But beware of erecting a wind turbine where the wind is not strong and steady. An area’s wind-speed, as well as the immediate terrain, will determine how well the wind turbine performs. If in doubt, we suggest starting with solar modules, and checking the wind for a year. This will show whether to add a wind turbine or more solar modules. Twelve to fifteen mph average year-round winds are necessary for an optimal installation, and these sites are not common. Wind turbines must mount at least 30 feet above trees and obstructions for 300 feet around. They need non-turbulent air where a weather vane holds a steady direction. Charge controls for wind turbines are…

We also carry books and DVDs to help you set up and benefit from micro hydro power. Micro-Hydro Advantages & Performance Water turbines steadily charge 12, 24, or 48 volt batteries, working 24 hours a day every day. Compare this with solar modules in sunshine for at best, 6 full-power hours a day, and that’s just on sunny days. A hydro generator producing 10 amperes around the clock matches the usable power generated by over 40 amps of solar modules. So cost is a lot lower with hydro. The power system itself is the same as solar, except only diversion type charge controls can be used with hydro. Pelton wheel generators use a small volume of water raised to high pressure by running downhill in a penstock (pipeline). Pressurized water shoots from nozzles to strike and spin a cupped wheel on an alternator. Other types of wheels and propellers handle water sites with less pressure (head) and more flow volume.

  • Charge ControllersCHOOSING A CHARGE CONTROLLER Charge controllers regulate the output of solar modules, wind generators and hydroelectric generators to prevent overcharging of the battery. For off grid solar power systems, when battery voltage rises to a preset maximum, where the battery is completely charged, the control automatically reduces or stops the solar charge. Some charge controllers are that simple, but most include some other features like volt & amp meters, voltage conversion, low battery load disconnect or night light timer. Read More VOLT AND AMPERE RATING OF THE CONTROL Select a control able to handle a little more than the amperes your solar modules are rated to generate. Though solar modules don’t usually produce more than their rated amperes, they can momentarily produce 15% more on cold bright days. The electric code recommends leaving a 25% margin, that is, for a 47 amp solar array use a 60 amp control rather than a 50 amp control. And if you plan future expansion of your solar array, allow a lot more headroom to accommodate the added solar panels. Be sure the model you choose is designed for your battery voltage: 12, 24 or 48 volts. A given control will handle twice as…
    • MPPT Charge ControllersMPPT Charge Controllers for Off Grid Living MPPT charge controllers employ DC to DC conversion, which allows the solar array voltage to be higher that the voltage required to charge the batteries. Many years ago solar modules were designed to charge 12 volt batteries. These solar modules were built with 36 cells in series to have a peak power voltage of 16- 18 volts. Two of these modules could be wired in series to charge a 24 volt battery and four could be wired in series for a 48 volt battery. Modules with 72 cells were also available for 24 volt charging. When all modules were made this way, the simple PWM charge controllers described previously worked fine. As connected off grid solar power systems became the prominent use for solar modules, cost became the most important factor in module design and off the grid homes. This lead to larger 60 cell modules, manufactured in a convenient size that could be carried by one person. These modules have a voltage too high for 12 volt battery charging and too low for 24 volt battery charging and are usually wired in series to get approximately 400 volts DC which is easy…

    • PWM Charge ControllersSERIES CHARGE CONTROLLERS – Connected between the charging source and the battery. Pulse width modulation (PWM), used in all modern charge controllers uses 3-stages of operation to give the most charging possible for the day. BULK charge is the first stage, where the maximum power available from the charging source is fed to the battery until it reaches a preset voltage. ABSORPTION is the second stage charge where the maximum battery voltage is held by reducing the charge current just enough to never exceed the target voltage. Reduced current is done by high speed on and off pulsing, where the controlling “on” time versus the “off” time of each pulse determines the average charge current. During this stage of charging there will be some bubbling, or gassing of the battery electrolyte. This is necessary to maintain the health of flooded batteries. FLOAT is a third stage where battery voltage is reduced after charge is complete. This avoids excessive evaporating of battery water and benefits battery life. When sealed, maintenance-free, AGM or gel type batteries are used, voltage set-points are lower to prevent gassing of the battery.

People using the largest solar power systems sometimes use AC power from an off grid inverter for everything. Usually it is most practical to use both inverter AC and some direct battery DC. AC is most practical for regular household outlets and lights, because most AC appliances are better quality, easier to find, locally available and lower priced than 12 volt DC versions. But a few special DC appliances can save a great deal of energy. Items that drain a small amount of power over long hours can use…

      • Diversion LoadsConnected between a battery and dump load. Diversion Charge Controllers are typically used when the charging source cannot be disconnected from the battery, such as wind generators or hydroelectric chargers for off the grid electricity. Diversion controllers do not cut off current from the charging source at all. When the battery charges to the maximum set voltage, the diversion controller connects a “dump load”such as ceramic air heating resistors or water heating elements to the battery to dissipate the energy coming from the charging source. The controller adjusts its consumption rate to offset the excess charging exactly, and keep the battery voltage at, and never exceeding, the preset maximum voltage. If you use a windmill for off grid living that does not have its own charge control, or use hydroelectric generating, a diversion control must be used, since those generators can be damaged if their charge is not absorbed in the batteries at all times. One diversion control handles a combination of solar, hydro and wind, so long as the total amps charge from all of them taken together is within its amp capacity.

    • LightingLighting for Off the Grid Homes LIGHT WITH LESS POWER Photovoltaics solar panels convert just 10% of sunlight’s energy into electricity. Ordinary light bulbs convert only 10% of that electricity back into light (the rest becomes heat in the bulb). Because lighting is a major part of power used in solar homes, special high efficiency bulbs that save 75% of the power are well justified. Read More COMPACT FLUORESCENT BULBS Compact fluorescent bulbs make far less heat and more light. Using one fourth the power of ordinary bulbs, a 15 watt CF has the brightness of a 60 watt incandescent. It runs 4 times as long on the same power. They give the same soft white light and should last as long as 6 ordinary bulbs. The cost of these lamps is much less than adding extra solar modules to run low cost incandescent bulbs.
