Installing Solar Panels Are Your Most Efficient Source Out Of All Renewable Energy Resources.
Different materials require a different amount of photon energy to produce the current in PV. Overall the ERoEI is high enough to justify costs based. The standard solar panel is made from Monocrystalline solar panel and Polycrystalline, Monocrystalline solar panel are slightly more expensive, but they are more efficient than Polycrystalline solar panels. The key difference between monocrystalline solar panel vs polycrystallines, is that polycrstalline solar panels are less efficient, with lower space-efficiency and they need to cover a larger surface for the same output as a Monocrystalline silicon panel. So based on your choices, efficiency can very which is widely, and is commonly misunderstood. Solar panels are becoming more efficient, based on statistics over time.

If you are interested in the prices, based on your system size, there is the HahaSmart price-checker, which analyzes your costs based on several factors including:
- Engineer / Permit
- Panel:by how many pieces
- Inverter & Accessory
- Racking
- BOS includes combiner box, solar cable, copper wire, AC disconnect, DC disconnect etc.
- Additionall you are looking at Hex bolt, T bolt, Flange nut, MC4 connector, J-box, Chemlink sealant etc.
- Sales Tax
Prices will show everything for home solar, including installation, for 25% below the average market value for rooftop solar.
