The costs for maintaining a solar power system are very low. Some components of the system may last decades without any maintenance at all.
Moreover when your solar power system generates power in excess of your own requirements, you may supply the excess power to the utility grid (and get paid for it). This system obviously will be costlier but has its own advantages.
Solar power systems permit you to plan for installation of a basic system and then carry on adding to it as you gain more experience and have less economic constraints.
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.
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.
If you house is already served by a utility supply, you may install a grid-connected solar power system with battery backup.
A solar power system is neither too dangerous nor too complicated for most people to run. It requires no supervision from the government or any other agency because it poses no risks.
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).
Solar power energy systems are not inexpensive. That said it's important to compare them within context of other types of home improvement projects.
Solar power systems have no moving parts to wear out or need lubrication. Once installed, solar power requires little attention. The user can almost forget it.
Nearly all countries around the globe have finally come to terms with the fact that changes in power usage customs will have to be made in the future. 1st October, 2009
