Keep in mind that purchasing a solar power system often enables you to receive tax credits from the government. You may find that you get back as much as 30 percent of the total cost of your system. So, if you look into a system and think that it costs too much, investigate whether or not you will get credit back to determine how affordable it actually is.
Check for government certification on any solar panel you are considering buying. Consider this tip a must. The government's seal of approval lets you know that these panels are deemed quality and efficient. Plus, some of the financial benefits of using solar panels (tax credits, etc.) rely on using certified panels.
When you can't afford a full system, instead start with a solar water heating system. Water heaters make up a large portion of the energy that a home consumes during the year. Your costs are going to be lower upon installation of your solar water heating system.
