No, not every solar panel needs a battery. Solar panels can function without batteries by feeding electricity directly into the grid or powering devices in real-time. However, batteries are beneficial for storing excess energy for use during non-sunny periods or power outages. Popular options include the Tesla Powerwall and GivEnergy batteries, both of which offer efficient and reliable energy storage solutions for residential and commercial solar systems.
Different panel manufacturers offer a variety of efficiencies, and the optimal panel for one installation may not be the best choice for another. For instance, a lower output panel with smaller dimensions might be more suitable if it allows for better coverage of the roof space compared to a larger, high output panel. As installers, we ensure that the panels chosen are tailored to the specific project, aligning with the business’s goals in the most efficient way possible.
Commercial solar panels generally range from 0.415kWp to 0.53kWp per panel. The total system size can vary widely based on the specific needs of the business, with commercial installations often ranging from 10kWp to thousands of Kilo Watts Peak.
All panel manufacturers have a range of efficiencies and the best panel for one installation may not be the best panel for another, for example a lower output panel that has smaller dimensions which allow the design to cover more of the roof space overall may be a better solution than a high output panel that is dimensionally bigger. As an installer we take care of matching the panel to the project to ensure that the business goals are met in the most efficient manner.
Commercial solar panels typically degrade at a rate of about 0.5% to 1% per year. This means that after 25 years, a high-quality panel might still operate at 80-90% of its original efficiency. Many manufacturers offer performance warranties guaranteeing certain efficiency levels over 25/30 years and the panel degradation expectations are detailed on its datasheet.
Solar panels can potentially increase the property value of a business, but they generally do not increase business rates (taxes). However, this can depend on local regulations, levels of self-consumption and how commercial properties are assessed.
Yes, some businesses and community clubs can often get grants, tax incentives such as Capital Allowances, and other financial assistance for installing solar panels. These can come from national and local governments, sport governing bodies such as FA RFU as well as utility companies. Additionally, there are lease and Power Purchase Agreement options available.
