Sample systems

A solar power system can cost anywhere from a few hundred dollars to charge devices and run small lights, to the sky is the limit. Typically, a cabin or home can run just fine on 5000 watts. The huge electricity eaters are heating and cooling. Propane is far less expensive than electricity. Many off-grid residents live in an RV which aleady has propane for heating and cooking. Air conditioners can use 5000 watts by themselves, whereas a swamp cooler (evaporative cooling) uses only a few hundred. But, if you really need that air conditioning, just add 5000 watts to the energy required.

In this first example, you have 1480 maximum watts constantly charging the battery bank during daylight. The 5000 watt inverter allows you to use up to 5000 watts, until the battery bank dies. In order to pull a constant 5000 watts, you need to charge a constant 5000 watts from solar, wind, or external generator. You can add batteries or solar panels at any time.

Typical off-grid kit
4 370 watt solar panels (1480 watts charging)
1 100 amp charge controller
1 5000 watt inverter
4 LiFeP04 batteries (24 volt bank)
wires, connectors, cables
$3,500.00

The above system does not include a solar panel rack. You can build one from 2x4s for about $100. The above system does not include installation. The above system will run a microwave, air compressor, computer, fridge, lights, etc. during the day. At night you are limited by your battery capacity of 200 ah. This is actyually quite a bit for night time, but if you need more power at night, you can add additional batteries at any time.

You can supplement solar with wind, which charges at night when the solar panels do not, if wind is frequent in your area.

Starter budget kit
1 370 watt solar panels (370 watts charging)
1 60 amp charge controller
1 12 volt 2000 watt inverter
1 LiFeP04 12 volt battery
wires, connectors, cables
$1,000.00

The above system will run a microwave during daylight. It will also run a computer, lights, and charge your devices. The price does not include a rack for the panel. The charge controller and inverter must be kept out of the weather. Warranty does not cover giving them a bath.

10,000 watt off-grid system
15 370 watt solar panels (370 watts charging) $4,500.00
1 180 amp charge controller included in inverter included
1 48 volt 10,000 watt inverter, single/split phase $1,995.00
1 48 volt LiFeP04 battery bank $7,500.00
wires, connectors, cables +$300.00
$14,295.00

The price of this system is expected to drop with the release of a new 48 volt power wall. This will replace the 48 volt battery bank listed above with a single battery. Please call or email for latest low price. This kit does not include a solar rack or installation.

We can do complete on site installations. You save money if you assemble the pieces yourself. A solar system is a lot like a flashlight. When the batteries are charged, everything works. The solar panels keep the batteries charged.
