Frequently Asked Solar Questions
Rooftop solar panels are installed with mounting systems either attached to the roof or ballasted with heavy blocks. Ballasted installations are used on flat roofs and require no penetration from the roof. For tilted or pitched roofs like asphalt, a small pilot hole is drilled into the truss of the roof frame. This pilot hole allows the mounting bracket to attach to the roof and the plate that holds the panel is flashed with the rest of the roof to prevent leaks. For metal roofs, clamps are used to hold the panels in place. In both cases, the panels and mounting system can withstand very high-powered wind loads and storms.
Home and business owners may realize a 10% ROI or better. Given their longevity, the systems may pay for themselves well within their lifetime. As energy prices continue to rise, the return on investment should also improve.
Expanding solar energy in our electrical supply is vital for a transition from a fossil fuel-based grid to renewable energy. Solar panels are mainly silicon, glass and wires. It is estimated that in just two years, the renewable energy produced by your solar PV system will exceed the embedded energy used in the production of the modules. The glass, wiring, and metal used in solar panels can be recycled for raw materials for future construction projects.
Your best starting point is to determine how many kilowatts of power you need is to look at how many kWhs (kilowatt hours) home, business, or organization used in each of the previous 12 months. With this, we can compare expected monthly solar energy production to your electricity usage. Annual electricity usage total is also a good start. You’ll find your monthly kWh records via paper copies of your utility bills, a phone call to your utility provider, or through your online utility account.
A south-facing area that gets sun from approximately 9 am to 3 pm is best. Solar systems also work well even when facing west or east, if that’s your best option. We can mount the systems on the majority of roof types, including a variety of materials used on pitched and flat roofs. Systems can also be ground-mounted.
Solar panels can last between 30-35 years, with manufacturers’ warranties typically lasting 25 years. Each year, the panel’s efficiency degrades by a small percentage. Yet after 25 years, high-efficiency panels produce 85-92% of the energy as they did in year one.
Illinois offers a special property tax assessment for solar. The alternative valuation will be the lesser of two values: the value of a conventional heating and cooling system, or the value of the solar energy system, whichever is less. Missouri’s property tax exemption for solar states that solar energy systems not held for resale are exempt from all state, local, and county property taxes.
Like plants and photosynthesis, solar panels take the power of the sun and turn it into energy. Here’s how it works. The photons from the sun shine down on the panels, they excite electrons in the panel’s cells, which then move to its circuits. This direct current energy travels from the roof to an inverter which converts the direct current (DC) energy to alternative current energy (AC) for your business’ energy use. The inverter connects to your business’ electrical system at the panel box or at the meter. In the installations StraightUp Solar completes, your business is always tied to the utility grid to receive power when the sun goes down. Your bi-directional meter tracks the energy generated from your array that exits your business as well as the energy your business consumes from the grid. When the grid is down, your inverter will not allow energy to exit your business to protect the utility workers repairing the lines.
StraightUp Solar works with a variety of top-tier solar energy equipment vendors. A portion of our solar components are sourced through our Amicus Solar Cooperative partnership, which allows us to obtain high-quality components with cost savings achieved through quantity.
