When discussing the subject of alterative energy it usually the topic of solar power that first springs to people’s minds.
Generally it's worth investigating the economic viability of installing a solar hot water system if you have an electric water heater with utility rates of at least 5 cents per kilowatt hour and have tax credits or rebates available. (It may even be worth changing out a gas-powered water heater if your costs are at least $8/million BTU).
The solar power inverter may look rather innocuous at first glance, however inside, its inner workings have to handle quite a bit.
Solar power is starting to break out of its stereotype as panels of silicon mounted on a roof.
Installing a solar home lighting system is done through the use of solar cells that convert solar power into electrical power in your home. The cells are charged with solar energy during the day that can then be used for lighting at night in your home. Another great way to save on your electric bill.
With a solar heating system in your home you will be able to cut down on the most expensive of electrical components in your residence.
Solar air heating panels are another system that saves energy, and is suitable for homes that can't use passive solar heating.
Although the first solar power cell was made with gold and selenium, it was much more inefficient than the silicon solar power cells of today.
Solar thermal systems capture the sun's energy to heat water and are one of the most cost-effective renewable energy systems. They are used to heat hot water tanks and/or a heating system. A solar pool heating system is another type of solar thermal system designed specifically to heat a pool or hot tub.
Solar power systems often get an additional financial boost as well: many jurisdictions and utilities across the USA offer attractive financial incentives to drive down the upfront capital costs associated with a solar power system.
