More and more people these days are installing solar panels or modules onto their rooftops. These solar panels or modules consist of several photovoltaic (PV) cells which are arranged in series and mounted onto a board. These photovoltaic cells transform photons in sunlight into usable electricity. Silicon, along with other elements like phosphorus and boron make up the semiconductor material found in most PV cells. This semiconductor material reacts to sunlight and releases a continuous charge. However, the solar panel generates only direct current hence you still need an inverter to convert it to alternating current to be used in powering household appliances.
One criticism of solar energy though is its variability. Shade and snow will expectedly cause decreased power output from the modules. This variability has been addressed with the integration of deep-cycle batteries as well as grid-tied systems.
The price tag on premade solar panels is probably the reason why homeowners are reluctant to have one installed. A single factory built panel can be around $900. Depending on your requirements, it can go to as high as $25,000 to 50,000. Some people find this too costly, others simply turn a blind eye on the startup cost and look to the long-term savings and earnings they can get from the system.
One of the advantages of using solar energy is that you can save a lot of money in the long run. In some countries, owners of grid-tied systems can even earn incentives from the government or from the energy company through net metering programs. Not only are you saving money but you are taking an active role in reducing our dependence to power sourced from fossil fuels which for a fact has contributed to global warming and climate change.
If you want to save a lot of money, you can build one on your own. Cost for homemade solar panel can be as little as $200 Materials and plans for solar panels can be found online. Those who are familiar with power tools and circuitry can build their own homemade solar panel systems in a day. If you aren’t as confident, there are available DIY packages online which contain plans for solar panels as well as video walkthroughs.
