Disadvantages of Solar Energy

Solar energy bring us a lot of benefit but there are also some disadvantages that we need to recognize. If we are aware all the aspects, the decision for our home energy system is more accurate.

The main disadvantage of solar energy is that it's dilute. This means you have to have a lot of solar collectors installed around your house. The energy itself is free, but the solar collectors are relatively expensive and some require regular maintenance in order to work properly and efficiently. If you decide to go solar you need to calculate the return on investment in order to know if the investment will be worth it.

DIY Home Energy Audits

In previous article, we just talked about Home Energy Audit. This post will show you how to carry out Do-It-Yourself Home Energy Audits. In fact, it is easy to conduct a DIY home energy audit by yourself. When auditing your home, keep a checklist of areas you have inspected and problems you found. This list will help you prioritize your energy efficiency upgrades.

How Solar Water Heating Systems Work?

Are you intend to install a Solar water heating systems for your home? And you may learn already how to install it and how much does it cost. And now we try to bring to you a very basic explain how a solar water heating system works.

Solar water heating systems use heat exchangers to transfer solar energy absorbed in solar collectors to the liquid or air used to heat water or a space.Heat exchangers can be made of steel, copper, bronze, stainless steel, aluminum, or cast iron. Solar heating systems usually use copper, because it is a good thermal conductor and has greater resistance to corrosion.

Solar Panels

There are several varieties of solar panels available on the market. The most common is a third generation silicon crystal panel. These panels are efficient enough to pay for their purchase price in 5-7 years of power production. This means you are essentially getting three to eight years of free power in the engineered lifetime of a solar panel. A newly emerging technology is the thin film solar array. This new technology allows solar panels to be made utilizing much less material than is needed for traditional methods. While they are less efficient currently than the more established crystal arrays, they also don’t need to produce nearly as much power to meet their production costs.
