Solar calculator

Solar land areaHow much we need solar power from our solar panel system to obtain enough money for our electric bill? We just want to gain some money from our residential (grid-tied PV) rooftop PV modules! How much sun do we need to make a home solar power system worthwhile? In general, the more sun a home solar power system gets, the better return will be. Or how much solar panels costs? Use solar energy calculator (CoolerPlanet) to estimate the cost and size of a solar power project in the USA area, only for a rough estimate,  and federal, state, or local solar incentives / rebates may not be included. Use this solar calculator in purpose to make a quick overview of future investment. For better understand PV systems, on the site Roof Solar Panels could be found more about Solar Energy! Therefore,  first, a costumer have to obtain Zip Code information of the state, it is available on the map below:

Enphase Energy Microinverter

Enphase Energy logoEnphase Energy Inc. (“Enphase”) ( is a privately-held enterprise based in Northern California (founded in 2006), led by experts in telecommunication, networking, software and solar products, and supported by leaders from throughout the solar power industry. Enphase Energy delivers solar power to homes and businesses with the microinverter system based on high-tech approach, making solar energy more productive, more reliable, and smarter.

As a pioneer of inverter technologies for the solar industry, we make solar simple and energy smart systems, creating a zero energy footprint. By combining solar energy with advantages of communications technology, all our products make solar power systems productive, reliable, smart and safe. That maens the energy harvest is increased by solar panels by up to 25 percent (technology improves the efficiency of solar cells arranged in modules). Solar microinverters are small devices that sit on a PV module, converting direct current, DC, from a solar panel into alternating, AC, current.

ANSOLE Days ( are being organized in a yearly international gathering by ANSOLE. It is a FORUM of knowledge exchange among non-experts, scientists, researchers and industrial experts, all of them are dedicated to promote the using of solar energy in particular and other forms (like off-grid PV systems and grid-tied PV systems) of renewable energies in Africa. Energy is an acute problem in Africa, so there is need to preserve and protect the environment. Therefore, the first ANSOLE DAYS 2012 with the topic “Solar Energy for Sustainable Development” will be held in Yaoundé (the administrative capital of Cameroon), from the 17th to the 19th of February 2012. The meeting will consist of fundamental sessions on various forms of solar energy conversation, oral and poster presentations of research results, presentations of networks in green energies and environmental protection, brain-storming round table discussions. African solar energy researchers are suitable for interdisciplinary interactions among african scientists, the only way to get out of the energy crisis, and our colleagues from abroad are going to support us and help in making better future for Africa.

Solar Energy Applications

Solar Decathlon Universität Darmstadt(In the photo is Solar Decathlon Universität Darmstadt) Modern society shows a development trend and an increasing consumption. This makes the cost of living to change. The equivalent price of a pleasant life is the energy consumed per capita. It is a statistical parameter showing quality of life through the consumed energy that a country uses for its assessment during the year. Therefore, a direct connection to the average amount of energy consumed and the quality of life in a country (community). Most developed societies consume the most energy, while the least poor. And very important is that consumption is increasing year by year. Some strategists say that until the 2040th energy consumption will increase by 300%.

This data may alert us as we are on the threshold, or have already entered the so-called “peak oil” – the maximum of production of oil. On the other hand, confidence in nuclear power is declining. Therefore, it is being spoken the energy crisis is approaching! Until we develop a reliable process for nuclear electricity generation, the solution is seen in alternative fuel sources – development of the renewable energy. There are certainly a leading sources of solar energy, wind energy, hydro energy, biofuels, waste treatment, geothermal energy, etc.. For that reason many efforts have been made in developing plants that will produce electricity from the listed energy sources.
