Making a solar panel power generating system and installing it in direct sunlight can produce usable electricity suitable for powering lights and appliances. Using photovoltaic solar cells placed in view of the Sun’s rays, collected energy is instantly converted into usable electricity. Producing direct current, solar power systems designed with “inverters” transform their power into alternating current, to support the energy requirements of most devices.
Inside a solar cell, light photons knocking electrons around cause an excited “photovoltaic effect.” First observed in the early 19th century, this heightened state of generated electrons inside the cell builds up a voltage between two opposing electrodes, creating electricity. This electrical current, from the Sun’s radiation, can then be directed through wiring, and instantly provide energy to support the electrical demand of an appliance or to recharge a battery.
The electrical output of a-solar panel is minimal. However, increased electrical power can be created by connecting multiple solar panels together in a series, forming a photovoltaic module. Practical use of a single module includes running single devices, such as an appliance, a phone or small electronic unit. To generate additional power, large enough to support a home, multiple modules need to be arranged in an array. It is quite easy to build an array large enough to support all the electrical demands a single-family residence requires around-the-clock.
To increase interest of the environmentally conscious public to invest funds in purchasing commercial solar power systems or crafting do-it-yourself solar panels, national government programs have been designed to offer tax credits as an incentive. These tax credits lower the overall upfront price of solar panel cost, help the environment by reducing conventional fossil fuel produced energy pollution and reduce or eliminate monthly utility bills.
Due to the current economic crisis, demand for alternative solutions to conventionally supplied electricity is on the rise. As more homeowners install a solar power system at their residence, the overall cost of photovoltaic modules decreases. The availability of generating free energy using renewable resources, such as solar power and wind power creates the opportunity to think “outside the box”. With the ability to convert DC electricity to AC, generated solar power energy can now be used to power off-the-grid applications in remote locations, on recreational vehicles, boats and cars.
For environmentally conscious do-it-yourself beginners and hobbyists, fabricating and installing handcrafted solar panels is a viable option. DIY solar power system information, schematics, guidelines and instructions can be found online at qualified websites. Easy-to-understand solar panel kits are also available on the Internet and can be assembled by any do-it-yourself beginner or novice.
