Keep Your Solar Panels Clean: Soiling Is a Drag On System Performance

Here's a look at the difference between clean and dirty solar panels. It may seem insignificant, but if left unattended, dirt and dust can drastically reduce a system's performance.

A number of factors impact the performance of solar photovoltaic (PV) panels, namely: (1) the size, number and efficiency of your solar PV panels, and (2) how much sunlight you get throughout the year. But there's an even more obvious factor that can impact a system's output: cleanliness.

New Feed in Tariff Report From NREL

Posted by Margaret Collins In Wednesday, February 3 2010 under: FIT, Feed In Tariff, NREL

In the interests of information-sharing, we just wanted to alert you to the National Renewable Energy Lab's (NREL) newly released report on feed in tariffs. It will make your knees weak if you're a policy wonk or an energy lawyer--I mean heck, it's entitled "Renewable Energy Prices in State-Level Feed-in Tariffs: Federal Law Constraints and Possible Solutions"--but it includes an overview for the FiT neophyte, as well. Don't read the whole thing, unless you're really, really having trouble sleeping, but do check out some basic definitions and context for the FiT programs developing across the country.

Government report offers guidance on new incentives

Up to their usual helpful tricks, the folks at the National Renewable Energy Laboratory (NREL) have once again teamed up with the Lawrence Berkeley National Lab to offer some much-needed guidance through the wealth of renewable energy incentive choices now available for commercial installations. They've just released a report that walks you through the differences among the feds' new incentives: the production tax credit, investment tax credit, and cash grant options. Since you can choose one but you can't choose them all, it helps to understand the real differences behind each option in determining which can be of most use to your business. Solar is not eligible for the production tax credit, but pretty much everything else is (geothermal, wind, biomass, hydroelectric, tidal...you get the picture).
