Components: Solar panels are made up of many individual solar cells, typically constructed from silicon. These cells are arranged in a grid-like pattern on the panel.
‍
Photovoltaic Effect: Solar cells operate based on the photovoltaic effect. When sunlight strikes the solar cells, it excites electrons in the silicon material, generating an electric current. This current is in the form of direct current (DC).
‍
Conversion to Usable Electricity: The DC electricity produced by the solar panels is then routed to an inverter. The inverter converts this DC electricity into alternating current (AC), which is the type of electricity used to power most home appliances and electrical systems.

Distribution and Use: The AC electricity can then be used to power your home or business. Any excess electricity produced can often be fed back into the local grid (in areas where net metering is available), potentially earning credits or compensation from your utility provider.

System Size: The total cost will depend on the size of the system you choose. Larger systems, designed to meet higher energy needs, will cost more. A standard residential system ranges from 5 kW to 10 kW, but custom-sized systems are available to match specific energy requirements.

Panel Type: There are different types of solar panels, including monocrystalline, polycrystalline, Thin film, Bifacial. Monocrystalline and Bifacial panels are generally more efficient and tend to be more expensive, while polycrystalline panels are usually less expensive but slightly less efficient. Thin-film panels are less common for residential use due to lower efficiency but can be an option for certain applications.

Installation Costs: Installation costs can vary based on your roof type, the complexity of the installation, and local labor rates.

Geographic Location: Costs can differ based on your location due to variations in local labor costs, permitting fees, and available incentives. Areas with higher solar adoption or lower labor costs may see reduced overall prices.

Incentives and Rebates: Federal, state, and local incentives can significantly reduce the upfront cost of solar panels. The federal STC rebate allows you to deduct a significant amount from the total cost of your system based on the area you live in. Additionally, some states offer rebates or other financial incentives that can lower the initial expense.

Financing Options: Solar panel costs can be managed through various financing options such as solar loans, leases, and power purchase agreements (PPAs). These options can reduce the upfront cost and provide different ways to pay for the system over time. Ask us how!

Additional Costs: Consider potential additional costs such as a solar battery storage system (if you choose to install one), upgrades to your electrical system, or ongoing maintenance

Electricity Bills: The primary way you save money is by reducing your electricity bills. Solar panels generate electricity from sunlight, which means you’ll rely less on your utility provider. Savings vary based on your location, energy consumption, and the size of your solar system. On average, homeowners can see reductions of 20-60% in their electricity bills.

System Size and Energy Needs: The size of the solar panel system you install will impact your savings. A system sized to meet all or most of your energy needs will result in higher savings compared to a smaller system. Your current energy consumption and the efficiency of your solar panels play significant roles.

Electricity Rates: Your local utility rates affect your savings. Higher electricity rates mean more substantial savings, as the cost of the electricity you’re offsetting with solar is higher.

Incentives and Rebates: Federal, state, and local incentives can significantly reduce the upfront cost of installing solar panels. These may include tax credits, rebates, and other financial incentives that can improve your return on investment and accelerate your savings.

Net Metering: In areas with net metering policies, you can receive credits for any excess electricity your solar panels produce and feed back into the grid. These credits can offset future electricity bills, increasing your overall savings.

Energy Prices and Inflation: As utility rates increase over time, your savings with solar panels can grow. Solar energy provides a fixed cost, whereas utility rates tend to rise, making solar an increasingly cost-effective option in the long run.

Property Value: Installing solar panels can also increase your property value, potentially leading to a higher return if you sell your home.

Maintenance Costs: Solar panels require minimal maintenance, so ongoing costs are generally low. However, keeping your system in good condition can ensure it operates efficiently and maximizes your savings.

Typical Lifespan: Most solar panels have a lifespan of 25 to 30 years. This estimate is based on the panels maintaining their efficiency over time. While panels continue to generate electricity beyond this period, their efficiency may gradually decrease.

Degradation Rate: Solar panels experience a gradual decrease in efficiency over time, known as degradation. On average, solar panels degrade at a rate of about 0.5% to 1% per year. This means that after 25 years, panels might still operate at around 75-85% of their original efficiency, depending on the degradation rate and panel quality.

Warranties: Most solar panels come with a performance warranty that guarantees they will produce a certain amount of electricity for a specified period. Common warranties are 25-30 years. In addition to performance warranties, manufacturers also provide product warranties that cover defects and other issues.

Durability: Solar panels are built to withstand various environmental conditions, including rain, snow, hail, and high winds. They are rigorously tested for durability and reliability, but extreme weather conditions or physical damage can affect their lifespan.

Maintenance: Solar panels require minimal maintenance to ensure their longevity. Regular cleaning and occasional inspections can help maintain their efficiency and prolong their lifespan. Most systems are designed to be low-maintenance, and manufacturers often provide guidelines for keeping panels in good condition.

Technological Advances: Advances in technology and materials may lead to improvements in the longevity and efficiency of solar panels. Newer panels might offer enhanced durability and performance compared to older models.

In summary, while solar panels have a typical lifespan of 25 to 30 years, they can continue to function beyond this period with reduced efficiency. Regular maintenance and proper care can help maximise their lifespan and ensure they continue to provide reliable energy generation for many years
