How To Choose The Right Solar System And Choose A Solar Panel

How To Choose The Right Solar System And Choose A Solar Panel | Sources are renewable energy resources and renewable. Solar thermal, photovoltaics, wind systems, which one to choose? My guide gives you the tools to know the nature of the three renewable resources, and guide you in choosing the solution that bests suits your needs.

Solar thermal systems can produce thermal energy by using solar radiation and through this facility you can have hot water for all domestic purposes. If the plant is large, it could be food or a complete heating system. Solar thermal systems have the highest yield in a cold climate with long winters and, therefore, if you have a house in the mountains, this is the right choice to make.

Solar PV system, using solar radiation, producing electricity for lighting, appliances and other electrical devices in the home. Someone must have a large space for installing photovoltaic systems, as they should be covered, even in part, by barriers such as chimneys, satellite dishes, trees. Solar PV systems suitable for electricity if your home is not accessible from the national grid.

Wind turbines generate electricity with low environmental impact by harnessing the power of wind. You better choose when to issue insulation, your home is not connected to electrical power. Furthermore, the area should be exposed to the wind of a certain size. If the content you need to be met, you can install a system called mini – wind.

How to Choose a Solar Panel 
The solar panel is a device to get the heat from the sun. These systems typically consist of a panel that absorbs energy from the sun, the heat transfer fluid that transports energy to heat exchangers and accumulators that store. Solar plant can operate with natural circulation (by convention) or forced (via pump).

Energy obtained can be used, not only for the production of sanitary hot water, but also for the integration of heating (with the best choice for the heat distribution system at low temperatures, such as the floor). Accumulator (minimum of 80 liters per square meter panel) has a goal to keep the hot water is not used directly, instead of making it available even when there are no operating conditions, such as at night. To ensure the desired temperature in any condition, then you should use a solar system integration with the boiler.

The most common solar panel there are two types: flat panels: they consist of a frame, covered on top with the sink located in a glass tube containing the fluid and heat transfer; vacuum panel: charge a small majority of flat panel and is formed by a series of glass tubes in the void created by increasing the insulation (air gap is the best thermal insulation) greatly reduces heat loss and improve efficiency. Determined both the size of the solar system for hot water needs of the user orientation, slope and type of solar panel.

If you live in northern Italy and your family consists of four people and an average consumption of 200 liters of hot water per day, you must install at least 4.4 square meter solar panel plan with the accumulator is not less than 250 liters. For the integration of solar thermal heating system, there should be a larger surface of the panel (up to three times if the plant has a tendency of greater than 40 ° or up to two times if this trend is less than 40 °).

This solution is advantageous when associated with the intervention of the thermal insulation of buildings and integrated with the heating at low temperatures. You must remember that for them to restructure or build a new building is required to install solar energy systems integrated into building structures were measured in a manner to provide at least 60% of domestic hot water building.

Forced-circulation kit is designed to cover an average of 70-80% of family needs 2-4 people may cost € 4000, which you must add a minimum of € 1500 for the installation. Natural circulation kit costs a little less, but it’s easier to install, but has a lower yield and accumulation occurs outside. Of coarse, for this type of equipment you can get tax breaks for the purchase and installation of solar thermal systems. This facility, the level of 55%, to get it as tax deduction on your tax return, you must start again in five consecutive annual installments no later than 60 thousand euro.
