WHAT IS SOLAR PV?
Solar PV, short for Photovoltaic (PV), involves the conversion of light into electricity. Interestingly, it's not just sunlight that drives this process; even on overcast days, these panels continue to generate electricity, albeit at a higher rate in brighter conditions. Remarkably, this technology isn't a recent innovation—it traces its roots back to the 19th century.
HOW MUCH WILL I SAVE ON MY BILL?
Atom Energy employs PV Sol software, a precise tool that factors in panel and inverter performance, shading, roof characteristics, and local weather data to forecast your electricity generation. Based on your typical energy consumption and the surplus energy returned to the grid, we provide estimates of both your electricity generation and potential earnings.
WHERE CAN I PUT SOLAR PANELS?
Solar panels are versatile in their installation possibilities. They can grace various rooftop types—from tiles and slate to metal and even turf. Moreover, they can integrate with structures like carports, canopies, and pergolas. Not limited to rooftops, solar panels can also be ground-mounted, ranging from small backyard arrays to expansive solar fields. Explore our solar PV mounting systems page for insights into diverse installation types or delve into specific installations through our solar case studies.
DOES SHADING AFFECT MY SOLAR PV?
Shading poses a significant challenge to solar PV performance. It not only diminishes the amount of light reaching the panels but also affects entire strings of panels due to their interconnected wiring. Employing sophisticated software, our designers evaluate shading effects and adjust designs to minimize its impact.
CAN I RUN MY HOUSE OFF SOLAR PANELS?
The feasibility of running your home solely on solar panels hinges on your electricity consumption. With an average household using about 3500 kWh annually (potentially halved with energy-efficient practices), a typical rooftop array in the UK, around 3 kWp in size, can generate approximately 2500 kWh per year. While it's feasible to produce more electricity than you consume annually and become a net exporter, bear in mind that solar generation doesn't perfectly align with household demand, especially considering reduced output in winter and nighttime dormancy. Additionally, it's worth noting that this calculation primarily covers lighting and appliance electricity and excludes energy demands for hot water, space heating, or emerging needs like electric vehicles.
HOW CAN SOLAR PV AFFECT MY ROOF WARRANTY?
In the realm of warranty concerns, commercial properties face more scrutiny than residential ones, particularly concerning the type of mounting system employed. Some roofing manufacturers also produce solar PV mounting systems. If your solar PV mounting system aligns with your roof manufacturer, your roof warranty should remain intact. In fact, in certain scenarios, your roof warranty might even extend by another 25 years to match the solar panels' warranty. However, if this alignment isn't the case—often the norm—installing solar panels could jeopardize your roof warranty.
DO SOLAR PANELS REQUIRE MAINTENANCE?
One of the most frequently asked questions about PV is maintenance requirements. When investing in solar energy, it's natural to wonder if additional expenses will arise for repairs. Generally, solar PV systems require minimal maintenance throughout their lifespan. Unlike other technologies, solar PV lacks moving parts, eliminating wear and lubrication needs. With a 25-year warranty and potential for even longer lifespans, solar panels are remarkably durable. Equipped with a surface coating facilitating water and dust runoff, panels are self-cleaning when pitched at greater than 10 degrees. However, in regions prone to excessive dust, debris, or bird droppings, panels may require cleaning. Hot water suffices for cleaning, but avoid abrasives or chemicals that could damage the specialized coating.
DO SOLAR PANELS AFFECT THE PRICE OF MY HOUSE?
The impact of solar PV on property value largely hinges on prospective buyers' perceptions. Nonetheless, solar PV enhances a property's energy performance rating (EPC rating). Increasingly, there's a correlation between energy efficiency and house prices in the same locale, with energy-efficient homes deemed more desirable. Even if you move from a property with solar PV, the new owner or occupant stands to benefit from reduced energy bills, a definite advantage. However, the quality of the installation matters. To maximize your property's value with solar, engage a reputable installer who can address future inquiries or concerns.
HOW DO SOLAR PANELS WORK?
Solar panels operate on the principles of semiconductor physics, specifically utilizing positively and negatively charged layers of silicon. When sunlight hits these cells, it releases electrons from the negatively charged layer. These free electrons migrate to the opposite surface, creating an electric current flow facilitated by collector wires, ultimately powering your appliances.
HOW LONG DO SOLAR PANELS TAKE TO INSTALL?
Installation duration varies based on the system's size. Typically, a residential solar PV installation requires a single day to complete, though more intricate setups might necessitate additional time. Excluding scaffolding, which typically requires a day for setup before installation and half a day for removal afterward in residential settings.
