Benefits of Solar

Solar energy provides a number of significant benefits that make it an appealing option for sustainable living. Firstly, solar energy is clean and renewable. Solar panel systems generate electricity from the sun rather than burning fossil fuels, which reduces greenhouse gas emissions and other forms of pollution. This makes solar a more environmentally-friendly energy source.

Solar can also increase energy independence by reducing reliance on the utility grid and non-renewable sources like coal and natural gas. With solar panels on your home, you become less dependent on fluctuating energy costs and foreign energy imports.

Additionally, solar energy can save homeowners money in the long run. Though solar panel systems involve an upfront investment, they can pay for themselves over time through electricity bill savings. Many homeowners see a return on their solar investment in as little as 5-10 years.

Evaluate Your Property

Before installing solar panels, you’ll need to assess if your home is suitable. The key factors to consider are your roof location, sunlight hours, angle/orientation, and system size needed. Ideally, your roof should face south and be angled between 15-40 degrees to maximize sunlight exposure. Track the number of direct sunlight hours your roof receives each day. At minimum, aim for 4-5 hours of strong sunlight daily.

Consider if your roof size and layout allows enough space for the number of panels needed. Most residential systems require 100-300 sq.ft of roof space. Use online tools or consult an installer to determine how many panels your household energy use requires. They will evaluate your roof size, layout, shading and obstructions to design a system to fit.

You’ll also need to check if your roof is structurally sound enough to hold solar panels. Make sure the roof’s age and condition can support the additional weight load, which is typically 3-6 lbs per sq.ft of panels. Regular roof maintenance may be needed prior to installation. With a suitable roof and solar access, your property will be ready for solar.

Choose a Solar System

Choosing the right solar system for your home is crucial to maximizing energy production and return on investment. There are a few key factors to consider when selecting a solar system:

Types of Solar Systems

The two main types of solar systems for homes are photovoltaic (PV) and solar thermal. PV systems convert sunlight into electricity through solar panels, while solar thermal systems use the sun’s energy for water heating. PV systems are more common for whole-home energy solutions.

System Size

Determine the appropriate system size by looking at your home’s energy usage and available roof space. A properly sized system will offset 60-100% of your energy needs. Work with a solar installer to calculate your home’s requirements.

Brands and Warranties

Look for reputable solar brands with a proven performance record. Compare product and power output warranties. Many panels come with 20-25 year power output warranties. Inverters, mounting equipment, and other components should also have at least 10 year warranties.

Researching the right system for your specific home is key to long-term solar success. Consult with installers to select the ideal setup for maximizing clean energy production.

Research Regulations and Permits

One of the key steps in installing a solar system is researching the regulations and permit requirements for your specific area. It’s important to look into any state or local solar laws, as well as your utility’s policies regarding grid-tied solar systems.

Most areas require permits for solar installations. Your local city or county permitting office can provide details on permit requirements, fees, and paperwork needed. Common permits include electrical, structural, and building permits. Many municipalities also require solar-specific permits.

Some key questions to ask your permitting office:

What permits are required for solar in my jurisdiction?
Are there any solar equipment certifications required?

Are there zoning or homeowner association requirements?
What are the fees for each permit?
What information and paperwork do I need to submit?

How long does the permit process take?

Understanding the legal requirements upfront will ensure your solar installation meets all regulations and avoids delays or complications down the road.

Calculate Costs and Incentives

Installing a solar energy system represents a major investment. Carefully calculating the upfront and ongoing costs, as well as any incentives or tax credits available, ensures the system pencils out financially.

Start by getting quotes from at least three reputable solar installers for the system size needed for your home. Quotes should provide a total installed price, as well as a breakdown of equipment and labor costs. Compare quotes to get the best deal.

Next, estimate the amount of electricity the system will generate each year in your location using solar calculator tools. Then multiply this by the cost per kWh of electricity from your utility to estimate annual savings on your energy bill. Account for future utility rate increases for a more accurate long-term savings projection.

There are several incentives that can offset the upfront cost of going solar. The federal solar tax credit offers a 26% credit for systems installed in 2022-2023, and 22% for systems installed in 2024-2032. Many states and utilities also offer additional rebates and credits. Be sure to research all available incentives.

Analyze the total cost savings over the system’s lifespan to calculate return on investment and determine if the project makes financial sense for your home. Sufficient savings and incentives should result in a reasonable payback period.

Select an Installer

Selecting a reputable solar installer is a key step in harnessing solar energy. Take the time to research and evaluate potential installers to find one that is licensed, experienced, and a good fit for your project.

Find licensed solar companies

Verify that any potential installers hold an active solar contractor’s license for your state. Most states require solar contractors to be licensed. You can check for active licenses through your state’s licensing board.

Compare multiple quotes

Get quotes from at least 3 licensed solar installers. Compare the system designs, equipment, warranties, prices and timelines. Be wary of quotes that seem too good to be true.

Verify credentials

Look for installers that are certified by the North American Board of Certified Energy Practitioners (NABCEP). This certification proves extensive solar training and expertise. Also verify how long the company has been in business and check online reviews.

Finalize Design and Contract

Once you’ve selected an installer, it’s time to agree on the final system design and sign a contract. Your installer will work with you to finalize the technical specifications, including the exact number and models of solar panels, inverters, racking equipment, etc. They’ll take into account your energy usage, roof layout, local regulations, and other factors. Often, they will provide a 3D model showing exactly how the system will be laid out.

You’ll also agree on the warranty terms, which often last 25 years for equipment and 10 years for workmanship. Understand exactly what’s covered so you don’t get caught with expensive repairs down the line.

In addition, make sure you’re satisfied with the remote monitoring capabilities. Many solar installers provide apps and web portals so you can view your system’s performance anytime. This allows you to monitor savings and troubleshoot any issues.

Finally, confirm the total costs and available incentives. Most solar loans and leases provide fixed monthly payments lasting 10-20 years. You’ll also likely receive tax credits and utility rebates to offset the upfront costs. Get all financial agreements in writing in your contract before signing.

With your final design nailed down and contract signed, you’re ready for the exciting installation process to begin!

System Installation Process

The solar panel installation process typically takes 1-3 days depending on the size of your system. Here is what you can expect during the installation process:

Schedule and Timeline

The installation crew will arrive on the scheduled install date and walk through the process with you. They will outline the timeline for that day and let you know what to expect at each stage. Usually, the order of operations is:

Staging and inspection of all materials/equipment
Roof work if needed (installing racking, rails, etc.)

Running conduit from roof to electrical panel
Mounting solar panels on roof
Electrical work (installing inverter, connecting to panel, meter install)

Startup and testing

The installers will make sure you understand what is happening throughout the process and address any questions or concerns you have along the way.

Roofing Work

If your solar panels require roof mounting, the installers will put a series of rails onto your roof secured by lag bolts into the rafters. These provide the base structure for the solar panels to attach to. The roof work is usually minimal, but may involve some holes drilled through exterior roofing. The installers will weatherproof and seal any penetrations to prevent leaks.

Electrical Work

Conduit will be run from your roof down to your electrical panel to connect the system. For grid-tied systems, your existing panel will also need an AC disconnect switch installed for the utility to access. If adding batteries, additional conduit will connect the battery enclosure to the panels and electrical panel. Finally, the solar inverter will be wired to your panel to allow AC power transfer. Your utility will need to do a final meter changeout after inspection.

Maintenance and Ongoing Savings

Once your solar panels are installed and operational, some simple maintenance is required to keep your system running efficiently for years to come. Here are a few key maintenance tips:

Keep panels clean – Dust, dirt, leaves, bird droppings etc. can accumulate on solar panels over time, reducing their productivity. It’s recommended to clean panels 2-4 times per year. Use a soft brush and mild detergent with water to gently clean the panels.

Monitor production – Most solar systems come with a monitoring app that shows how much energy your system is producing in real-time and historically. Keep an eye on production to make sure your system is performing as expected.

Realize utility bill savings – One of the biggest benefits of going solar is reducing or eliminating your electric bill. Monitor your utility bills in the months after installation to ensure you’re getting the cost savings you expected. Anything less may indicate an issue.

With just a little bit of maintenance and monitoring, your solar system will provide clean, renewable energy and utility savings for decades. Going solar is a great way to reduce your environmental impact and energy costs.
