Solar panels are available in various capacities, qualities, prices and features. The perfect solar panel for your home and your needs may be very different from those of your neighbors. Consider the following criteria when deciding which one will suit your needs.
Solar panel prices.
The average cost of a home solar system is about $16,000, ranging from $3,500 to $ 35,000 including installation and panels, and no tax credits are used. While quality plays a role in the cost of solar panels, the features and capabilities of the individual system components are also important. Look for solar panels that provide the highest return on investment and allow you to lower your energy costs while staying within your budget.
panel efficiency
Efficiency figures are expressed as a percentage, reflecting the efficiency of each solar panel. The current average efficiency rating for residential panels is around 18%. High-efficiency solar panels have an efficiency of just over 22%, while budget products have an efficiency of about 16%.
Not every home needs the highest possible efficiency rating. Your budget, power requirements, and available space will help determine acceptable efficiency ranges. When buying, keep in mind that the efficiency of solar panels decreases slightly over time.
panel power
To be useful, solar panels must produce as much energy as they replace. While the efficiency rating reflects how well the panel converts energy into energy, output measures the result in terms of energy. Most modern residential solar panel systems produce between 250 and 400 watt hours. Generally, high voltage panels are preferred over low voltage panels. However, when determining panel power per watt, consider your needs and budget.
temperature coefficient
The panel rating factor measures the loss of efficiency as the temperature rises and is expressed as a negative percentage. Ratings with lower temperature coefficients represent solar panels that perform better in warmer climates than panels with higher coefficients. While low factor panels can be important in hot climates, they can also work well in areas with extreme temperature changes.
Your home needs energy
Depending on your home's power consumption, you may need a home solar system that generates more or less electricity. Make sure your system generates enough electricity during the day and keep it running all night if you wish. Some solar energy users are opting for systems that are large enough to produce enough power to meet some of their needs, while others are opting for systems that allow them to live off the grid and even sell power to local energy providers.
Check Solar Panel Warranty
A typical solar panel brand product warranty is 25 years. Warranties for system components such as batteries, inverters, and other critical components often vary greatly by product and manufacturer. Look out for these warranties and the 10 and 25 year warranties for panel outlets, especially if you plan to live in the same house for a long time. Look for performance warranties and manufacturer warranties.
Availability of an installation company
Make sure the installer you choose offers the panels and system components you need, or equivalent, no matter where you live. Check reviews, recommendations and quotes when choosing a company that can meet your solar energy needs. Look for a labor warranty from the installer in addition to the manufacturer's warranty.
available rooftop space
The amount of rooftop or patio space you have with optimal orientation is a major factor that can limit your choice of panels. Small spaces benefit from fewer panels with higher power and efficiency, while homeowners with more space can take advantage of more panels and power options.
View Solar Panel Reviews
Not so long ago, some solar energy consumers are looking for experience. That all changed when solar gained popularity and now consumers have had several years to evaluate their systems. Online reviews of solar panel manufacturers, models, installers, systems, warehouses and other components are readily available so you can be sure you are investing for the best results.
Recommend solar installation
Solar energy systems and solar battery systems are constantly evolving and improving. When making a purchasing decision, ask other experienced people who have the system you are considering what they have learned. Also, be open to recommendations from solar companies regarding your energy needs. In an ever-changing industry, there is always new information that can be useful.
