It is important to realize that photovoltaic power systems are expensive when compared with the low price of utility power in North America and the rest of the world. Normally.

You should reserve the electric power produced by photovoltaic modules for your most energy-efficient appliances, tools, lights, etc.

Although it is technically possible, heating with photovoltaic systems is generally not recommended. You can easily and more efficiently collect heat with a solar thermal system.

A solar water heater or a solar pool heater, as mentioned earlier, generates more hot water with less initial cost than any photovoltaic-powered heater.

Also, for cooking, it is normally more cost-effective and convenient to use a stove that operates on propane or natural gas rather than solar electricity.

Stand alone solar-powered homes and cottages often rely on wood cook stoves for cooking and space heating. Refrigerators are becoming more energy efficient, so the cost of operating them with solar power is now feasible. There are some great energy-efficient products now.

From an economic point of view, first consider investing in energy-efficient electric AC appliances, and then size your photovoltaic system based on actual consumption (read our post on How to Size your Home Made Renewable Energy System). For example, using compact fluorescent lights will reduce your electrical consumption for lighting by 80 percent or more.

In our next post we will discuss the types of solar panels to choose. Stay tuned

In 1979, the developer of a condominium village in New Hampshire decided to bring an environmentally responsive alternative to the market. He designed the building to use solar energy. The solar panels were made of glass, offering a beautify view of the scenery. Buyers responded very well, leading the developer to design several more similar buildings.

Construction began in 2007 in Boulder Colorado on a project called Solar Row. The project consists of thirteen homes using only solar power. This will be the first solar home development project in the Boulder area. The design of each home has been carefully set up to allow the home to use and creates its own energy.

Some states are pushing for solar powered housing. California officials are proposing half of all new homes build run on solar energy in within ten years. They are pushing for solar homes to prevent further issues with energy crisis. Three years ago utility customers had difficulty paying their electric bills because of the high cost. Officials plan to give rebates to home builders who agree to install solar panels on new homes. They may offer incentives for installing panels on existing homes as well. Environmental groups are backing California’s proposal as they fill it will encourage other states to follow. It is believed that if many states decide to implement such programs, then the cost of setting up solar power will greatly decrease.

However, many environmental groups aren’t willing to wait around to see what California decides to do. They have taken solar power issues to the legislation. A solar incentive bill has been approved by the Senate. It is still pending with the Assembly Committee. If approved, it would require fifteen percent of new homes being built are complete with solar panels beginning in 2010. The goal would be for the rate to increase each year by ten percent until it reaches fifty five percent.

The building industry opposes the promotion of solar homes. They are against the legislative bill. However, many in the building industry agree that solar homes could lead to economic and atmospheric improvements. The many concern of the building industry is the additional cost to them to meet the solar powered home requirements. If Congress is willing to give them monetary incentives to help reduce these costs, the issue could likely be resolved. It is estimated on average that addition solar power equipment to a home will cost $17,000 to $20,000.
