Solar panels (photovoltaic panels) convert light into electricity. Usually on a roof of a house they mounted systems can be installed and a solar tracking system are to improve efficiency. The electricity produced, both for commercial solar cells or homemade solar panels, is a battery and / or DC-AC inverter-fed. Many smaller applications, boats and recreational vehicles do not drive. With sufficient power, a system capable of providing all the electricity in your homeNeeds. However, the investment is considerable. The installation of a 6-week comprehensive home can cost more than $ 40,000.
With the brand Coleman ICP produces glass plates covered with a plastic frame weather-resistant, cables, leads to the battery (to avoid overload), a charge controller and protection diode to prevent discharge into the night. Your cells are made of amorphous silicon. Even if the panels are much smaller for small applications available to use for the products include a full-scale 130-WSolar Charger with 8 amps of 16.5 V output at a price of about $ 1,000. The dimensions are 59.75 "x 28.5". Two windows to the 260W costs about $ 2000 and provides three options panel provides 390 W for your jumbo-camper or boat $ 3000. In just over a week for a cabin would be nine grid panels for more than $ 9,000. Six weeks for a house would cost $ 15,000.
Homemade solar panels can save $ 10,000 or more the cost of wood. Multi-crystalline silicon solar cells become available at a lower priceat $ 0.10 / W. For example, a package is ($ 1.38/cell) of 138 solar panels for about $ 190 each 3 "x 6" cell delivers 1.7 watts of 3.5 amps to 0.5 volts corresponds to 100 MW / sq inch the normal output for multi-crystalline silicon solar cell. The cell size can vary, but MW / m not inches. This means a cost of $ 0.80 / W.
A huge pot (17 sq m) with 138 cells would be 235 kW. However, a configuration more manageable, two 39 "x 39" (8.5 m) panels of each delivery118 W. Another possibility would be three 29 "x 29" panels (5.7 square meters) will offer 78 W each. Six orders flat enough to generate nearly 1.4 KW for $ 1,141, enough to make serious dent in your electricity bill or the performance of a hut. A whole house (6 KW) may be supplied with solar energy in the house for about $ 5000.
At a price of $ 220 or 15% more, a DIY kit for the above package includes cells (138), 150 'wire Tab, 25' wire bus, diodes 6A and pens flow. Comparison with the cost$ 15,000 for 6 KW of solar panels Coleman. In addition, multi-crystalline cells, compared with solar modules Coleman amorphous silicon cells require more time. In general, the life of a new roof or more matches. Of course, the wiring in the home solar panels, and require the construction of a frame.
