Factors to Consider BEFORE going Solar
Switching to solar energy is a fantastic way to reduce your carbon footprint and save on electricity bills. However, not every home is a perfect candidate for solar panel installation. Before you invest in solar energy, it's crucial to understand the factors that could disqualify your home from being a suitable location for solar panels. Here are some key considerations:
1. Older Roof
Why It Matters
Your roof is the foundation for your solar panel system. If your roof is nearing the end of its lifespan, installing solar panels on it might not be wise. An older roof could require replacement soon after the panels are installed, leading to additional costs and complexities.
What to Check
Age of Roof: Typically, if your roof is more than 10-15 years old, it should be inspected to determine if it can support solar panels. (depending on type)
Condition: Look for signs of wear and tear, such as missing shingles, leaks, or structural damage.
2. Lack of Roof Real Estate
Why It Matters
Solar panels require a significant amount of space to generate enough energy to be cost-effective. If your roof doesn’t have enough clear, unobstructed space, you may not be able to install a system that meets your energy needs. Typically, a standard sized 10 kW system is advisable for most PV Systems. Panels are around 400-410 watts, meaning your roof would need 25 panels to reach a 10 kW system.
Additionally, for optimal solar panel production, a south-facing roof is the best option, followed by an east-facing roof, then a west-facing roof, and lastly, the least productive, a north-facing roof. That being said, panels placed on the North Facing roof will have a lower return on investment.
What to Check
Roof Size: Measure the available space on your roof. A typical solar panel is about 5.5 feet by 3.5 feet.
Obstructions: Chimneys, skylights, vents, and other roof structures can limit available space.
Orientation and Tilt: Ideally, solar panels should face south in the Northern Hemisphere, with a tilt angle that maximizes sun exposure.
3. Main Service Panel is Old and Outdated
Why It Matters
The main service panel distributes electricity throughout your home. If it’s old or outdated, it might not handle the additional load from a solar power system, posing a safety risk and potentially requiring expensive upgrades. This also causes inefficiency regarding electric usage, which is counterintuitive with the goal of solar. In todays market there are now Smart panels that allow for access to assess your home’s consumption in a highly detailed manner. To lear more visit https://www.solarfirst.us/energy-management
What to Check
Panel Capacity: Check the amperage rating of your main service panel. A typical modern home requires a 200-amp service panel for solar integration.
Condition: Inspect for signs of wear, corrosion, or outdated technology that might not support modern electrical systems.
4. Sub Panel is Overloaded
Why It Matters
The sub panel works in conjunction with your main service panel to distribute electricity. If it’s already overloaded, adding solar could lead to electrical failures and potential hazards. This will also lead to issues regarding inspections based on the risks if solar is done prior to upgrading sub panel.
What to Check
Load Analysis: An electrician can perform a load analysis to determine if your sub panel can handle the additional power from solar panels.
Upgrades Needed: Identify if upgrading the sub panel is necessary and factor in these costs before deciding on solar installation.
Additional Considerations
Roof Shading
Trees, buildings, or other structures casting shadows on your roof can significantly reduce the efficiency of solar panels. Assess the shading throughout the day and year to ensure optimal sunlight exposure.
Local Regulations and Permits
Some municipalities have strict regulations and permit requirements for solar panel installations. Check with your local government and homeowners’ association (HOA) for any restrictions or requirements. Florida Statute 163.04 forbids any binding agreement (between HOAs or otherwise) to prohibit a property owner from installing solar. An HOA may restrict where you place your solar panels, but not if the system’s performance suffers as a result. Although this statute is in place, HOA’s may have additional hurdles to go through before going solar.
Conclusion
While solar energy offers many benefits, it’s not suitable for every home. Evaluating these factors can help you make an informed decision and avoid costly mistakes. If your home doesn’t currently qualify, consider addressing these issues where possible or explore alternative renewable energy solutions that might better fit your situation. By ensuring your home is ready for solar, you can fully enjoy the environmental and financial benefits that solar energy provides.
