The output power of solar photovoltaic system is generally difficult to reach the nominal power of the module, because the power of the module is tested under very good weather conditions and the temperature of the module is relatively low. Normal weather is not able to achieve this condition, photovoltaic modules may not all receive solar energy, because the photovoltaic system has losses. In this article, Home Power Inverter will tell you more.
The solar panel role in the solar photovoltaic system, is just to convert sun-light to DC electricity, it cannot store energy, so we use batteries to store electrical energy at the time of excess solar light to be used at the times of no solar light. Mainly in most of places, there are 2 types of solar photovoltaic systems to be used. The first is the grid tie solar system, in which extra generated electricity will be sent back to the electrical grid, and then the solar system owner takes credits from the electric grid to be used in his future bill, and saving his money.
Solar photovoltaic system consists of solar cell, solar controller and battery. Solar panel is the core part of solar photovoltaic system, the role of solar panel is to convert the sun's light energy into electric energy, output direct current into storage battery. Photovoltaics is an electronic process that occurs naturally in semiconductor materials. When sunlight hits semiconductor materials, electrons are released and can travel through circuits, producing electricity that powers our electrical devices.
The connection of the solar photo-voltaic system to the power grid has multiple ways, based on electric utility regulations, and solar system owner installation purpose.
One of these connection ways is the gross metering scheme. In this scheme, the whole electricity generated form the solar photo-voltaic system will go directly to the grid, and not to our home. So, all the harvest will be sent back to the grid on a pre-determined feed in tariff we agreed for with our local electricity supplier.
We can confirm that solar panel size will be indicated based on the solar system application available space installation area, as if you have a small area in which you will install the solar system, then small size solar panel with high efficiency will be considered which will cost a bit higher, but for large areas, we can sacrifice with the high efficiency factor, and buy larger size solar panel with lower efficiency and of course it will be price cheaper.
