Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That’s why it’s crucial to accurately gauge the size of the solar energy system needed for your home by figuring out your average energy use.The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
