Solar Panels

More Information about Solar Panels

Among portable solar panel systems for use in places that are off the electric grid, and among large-scale array systems for homes or businesses, there are also intelligent building-integrated photovoltaic systems that permit buildings to style themselves as they see fit, whether for historic reasons or to allow architects to do their jobs.

The solar energy production payoff goes beyond planetary perks, bringing a handful of solar power system benefits to homeowners' doorsteps. Most importantly, renewable energy promises to reduce our reliance on finite fossil fuels and even nuclear power. On a smaller scale, solar power might help reduce the cost of living at home with lower electricity bills. As the cost of solar paneling continues to drop, the number of people using this technology, either on their homes or businesses, appears to be rising. Whether powering vehicles, residences, or commercial properties, those rooftop panels seem increasingly vital to our sunny energy future.

FAQs

Do solar companies provide solar loans to help with solar panel cost?

Yes, many solar companies offer financing options such as solar loans to help customers with the upfront cost of installing high quality solar panels. These loans can have different terms and interest rates, so it's important to compare and choose the one that best fits your needs and budget. Some solar companies also offer leasing options, where you pay a monthly fee for the use of the solar panels rather than buying them outright.

What is the average solar panel capacity and what energy storage device is most commonly used to store excess solar energy?

The average solar panel capacity ranges from 250 to 400 watts per panel, and lithium-ion batteries are the most commonly used energy storage devices for storing excess solar energy.

Does the National Renewable Energy Laboratory install solar panels in a PV system?

The National Renewable Energy Laboratory (NREL) focuses on research and development of renewable energy technologies and does not offer solar panel installation services.

Solar Installation Tips and Tricks 

Important things to consider when setting up a solar system:

Properly calculate energy needs

It is important to make sure not to underestimate how much power is being consumed by the system. This is especially important for any sites that are completely off grid, like a water tank that is monitoring various values at a given location. It is not uncommon to see these tanks located in areas that have no access to utility power. In these types of situations, it is critical to make sure that the total energy consumption has been calculated properly. So make sure to take time up front and properly calculate the amount of power that is required, and add a safety factor to the calculation in order to provide excess power in case things change in the future.

Battery backup

Battery power is essential when solar panels are not producing enough energy for critical operations. Solar panels only generate power when they are in direct sunlight. Night time, winter and times of inclement weather require an alternate source of power.   

When in doubt, go big

It is always better to oversize when planning a solar system and determining power requirements.
