We have Solar Panels and Solar Energy Options for everyone and every type of budget!
The solar panel (or photovoltaic component) is the heart of the system. It transforms the sun's rays into useable, renewable electrical energy. The solar panel (or module) is comprised of several individual photovoltaic cells connected in series or parallel. The energy produced by a solar panel is influenced primarily by the number of cells within a panel and how these cells are arranged within the panel. When the cells are connected in series the total voltage is the sum of the voltages from each individual cell. The output current in this configuration will remain the same as that produced from a single cell.
When the cells are connected in parallel, the total current is the sum of the currents from the individual cells and the output voltage is the same as that produced from a single cell.
Solar panels can be arranged to produce a specific current and voltage. By connecting solar panels in certain configurations (called a solar array), one can dictate the current and voltage of the solar array, thus dictating the electricity the system produces.
Frequently Asked Questions
Do solar cells store energy?
No. Solar cells convert sunlight into an electric current that must be used immediately or stored in batteries for later use.
How well do solar panels work in cloudy conditions?
A cloudy day provides sufficient diffuse light by which the panel will produce electricity. Optimum electrical production occurs with bright and sunny weather conditions. In remote, off-grid applications, a PV system is connected to a battery storage system as a backup power source. In grid-connected applications, the PV system works in parallel with the utility power grid. So, if electrical needs exceed the solar power output, the local utility makes up for the shortfall. Conversely, when the PV system generates more energy than the building requires, the excess power is exported to the utility grid, reversing the electrical meter and you receive payment from your local power company!
Can I use equipment directly from solar panels?
Yes. Solar panels will directly power equipment such as fans and pumps as long as the load is accounted for correctly.
What type of maintenance is required on solar panels?
Solar panels have no moving parts to wear out, they can be used alone or in combination with other energy sources, they are silent, reliable and long lasting.
