Flashing for Solar Electric Mounting Points The connections of a solar array to your roof are crucial for a successful long-term, trouble-free solar electricity installation. These connection points to your home/roof need to be flashed and waterproofed properly using standard roofing practices. These will look very similar to the other flashings around your existing [...] I get quite a few questions about and see a lot of articles on “thin film” for solar electricity. And many of these articles seems to cause more confusion than help explain what “thin film” solar actually is and is not. Thin film is just a thin layer of semiconductor material deposited onto a base [...] On a regular basis I hear or read there is a new solar “whatcha-ma-gadget” (or fill in the blank). It is typically some new, fantastic, incredible, unbelievable, “wizbang” technology. It’s never available right now, but will be “sometime soon”. Unfortunately, I have not yet seen one of these materialize. It has always turned out to [...] Have you ever thought of a solar PhotoVoltaic (PV) system as an investment? Looking at it this way is an excellent way to analyze whether it is worth buying a solar electric system or not. Start with considering the amount of money spent on a system, which includes the purchase price (or down payment and [...] For the most part it is because no one has explained how it works and what all of the advantages are. State rebates, federal tax credits, net metering agreements all make solar electricity very attractive. Additionally, solar panel prices have dropped significantly, which makes them much more affordable and easier to make a [...] You’ve probably asking yourself: Sure, this “Solar Electricity” sounds great but how does it actually lower my electric bill? Instead of buying 100% of your electricity from SDG&E, your solar electric panels produce part or all of your electricity, just as you would expect. In the end, you end up buying less electricity and [...] It could be, BUT !!!!!!!!!! I don’t recommend it unless you have a LOT of experience with electricity and working on roofs. This is one of those times that for most people it’s probably best to hire a professional that specializes in Solar Photovoltaic Systems (PV). I strongly recommend finding someone who focuses exclusively on [...] In my last entry, I discussed how the Sun affects your life every day and how you can harness a bit of that energy to reduce your monthly electric bill. The basic idea is that a solar electric system captures the sun’s energy and converts it into electricity that you can use in your home. [...] When was the last time you thought about the sun? The sun is one of the most powerful forces in our everyday lives. Yet we rarely think about it. Our sense of day and night is from the sun. The natural cycles of spring, summer, winter, and fall every year are created by the sun. [...] A grid-intertie is simply a connection from your solar electric system to the electric company’s power distribution “grid”. But what does this mean? What are the implications? One of the main advantages of a grid inter-tie is that you have electricity available whether the sun is up or not; and without a battery backup system. [...] |
