Get Clear Answers to Common Questions About Going Solar
Thinking about going solar? You probably have questions. We’ve compiled answers to the most common questions we hear from homeowners and businesses considering solar energy.
Getting Started
Q: How do I know if my home is right for solar?
A: Your home is likely a good candidate if you have:
- A roof with 6+ hours of daily sun exposure
- A roof in good condition (10+ years remaining lifespan)
- Monthly electric bills of $100 or more
- Ownership of your property (or landlord permission)
Even homes with some shading can work with proper system design. We provide free site assessments to evaluate your specific situation.
Q: How much will a solar system cost?
A: Residential solar systems typically range from $15,000 to $35,000 before incentives, depending on system size and complexity. After the 30% federal tax credit, costs drop to $10,500-$24,500. Most homeowners see payback within 6-10 years, followed by 15-20 years of virtually free electricity.
Q: What size system do I need?
A: System size depends on your energy usage, roof space, and goals. The average home needs an 8-10 kW system, but we custom-design every installation based on your specific needs. We’ll analyze 12 months of your utility bills to determine the optimal system size.
Q: Can I get solar if I don’t have cash to pay upfront?
A: Absolutely! Solar financing options include:
- Solar loans with $0 down and low monthly payments
- Home equity loans or HELOCs
- PACE financing (Property Assessed Clean Energy)
Many customers find their monthly loan payment is less than their previous electric bill, making solar cash-flow positive from day one.
Financial Questions
Q: What is the 30% federal solar tax credit?
A: The Investment Tax Credit (ITC) allows you to deduct 30% of your solar system cost from your federal taxes. For a $25,000 system, that’s a $7,500 tax credit. This credit is available through 2032, then decreases to 26% in 2033 and 22% in 2034.
Q: Are there other incentives besides the federal tax credit?
A: Yes! Additional incentives may include:
- State tax credits or rebates
- Utility company incentives
- Property tax exemptions
- Sales tax exemptions
- Business tax benefits (MACRS depreciation)
- Solar Renewable Energy Certificates (SRECs)
We help you identify and capture every available incentive to maximize your savings.
Q: What’s the return on investment for solar?
A: Most solar systems pay for themselves in 6-10 years through electric bill savings. After that, you enjoy 15-20 years of nearly free electricity. Over 25 years, typical homeowners save $30,000-$75,000 compared to staying on the grid.
Q: Will solar increase my property value?
A: Studies show solar panels increase home values by an average of 4.1%, or about $15,000 for a median-priced home. Solar-equipped homes also sell faster than comparable homes without solar.
Q: What if I sell my house before the system pays for itself?
A: Solar systems transfer with the property and increase its market value. Buyers love the benefit of lower electric bills. Many realtors report solar homes sell faster and for higher prices than comparable non-solar homes.
System Design & Installation
Q: How long does installation take?
A: The physical installation typically takes 1-3 days. The full process from signing a contract to system activation takes 2-4 months and includes:
- System design and permitting (3-6 weeks)
- Equipment procurement (2-4 weeks)
- Installation (1-3 days)
- Inspection and utility approval (2-4 weeks)
Q: Will solar panels damage my roof?
A: No. Professional installers use proven mounting systems that protect your roof. Panels are attached to the roof structure (rafters), not just the shingles, with proper flashing to prevent leaks. Many installers offer roof warranties in addition to the solar warranties.
Q: What happens if my roof needs repair?
A: Solar panels can be temporarily removed, your roof repaired, and panels reinstalled. While there’s a cost to do this (typically $1,500-$3,000), it’s uncommon. Most customers replace roofs before installing solar if the roof has less than 10 years of life remaining.
Q: Can I add more panels later?
A: Yes, systems can usually be expanded if designed with this in mind. We always discuss future energy needs and can engineer systems to accommodate expansion for electric vehicles, home additions, or increased usage.
Q: Do I need to replace my electrical panel?
A: Not always, but sometimes yes. Older homes with 100-amp service may need a panel upgrade to accommodate solar. We assess your electrical system during the site visit and include any necessary upgrades in your proposal.
System Performance
Q: How much electricity will my system produce?
A: Production depends on your location, roof orientation, and system size. A typical 8kW system produces 10,000-13,000 kWh annually, enough to offset most or all of an average home’s electricity usage. We provide detailed production estimates using your specific roof characteristics.
Q: What happens on cloudy days?
A: Panels still generate electricity on cloudy days, just at reduced output (10-25% of normal). Your annual production estimate accounts for seasonal variations and weather patterns. Most systems produce excess energy in summer that offsets lower winter production.
Q: What happens at night?
A: Without batteries, you draw power from the grid at night (if you’re grid-tied). With battery backup, you use stored solar energy. Net metering credits earned during the day offset nighttime grid usage, so your bill stays low even without batteries.
Q: How long do solar panels last?
A: Solar panels typically last 30-40 years. Most come with 25-year performance warranties guaranteeing 85-90% of original output after 25 years. Actual degradation is usually less than 0.5% per year.
Q: Do solar panels require maintenance?
A: Solar panels require minimal maintenance. Rain usually keeps them clean, though occasional washing improves performance in dusty areas. We recommend annual professional inspections to ensure optimal performance. There are no moving parts to wear out.
Q: What about snow and hail?
A: Solar panels are tested to withstand 1-inch hail at 50 mph. Snow typically slides off tilted panels, but heavy accumulation can temporarily reduce production. Annual production estimates account for seasonal snow coverage in your area.
Backup Power & Batteries
Q: Will I have power during a grid outage?
A: Grid-tied systems without batteries shut down during outages for safety (to protect utility workers). Systems with battery backup continue operating during outages, powering your home from stored solar energy and batteries.
Q: How much does battery backup cost?
A: Battery systems typically add $10,000-$18,000 to your solar installation, depending on capacity. A single battery (10-13.5 kWh) can power essential appliances for 1-2 days. Multiple batteries provide extended backup or whole-home power.
Q: Can I go completely off-grid?
A: Yes, but it requires larger battery banks and lifestyle adjustments. Off-grid systems cost $40,000-$80,000+ for an average home and require careful energy management. Most customers find grid-tied systems with battery backup offer the best value and flexibility.
Q: Can batteries be added later?
A: Yes, most modern solar inverters can accommodate battery additions. It’s more cost-effective to install batteries during initial installation, but retrofitting is possible if your system was designed to support it.
Net Metering & Utility Questions
Q: What is net metering?
A: Net metering is a billing mechanism where excess solar energy you produce is sent to the grid in exchange for credits. When you need more power than your panels produce (at night), you use those credits instead of paying full price for electricity.
Q: Will I still have an electric bill?
A: Most likely yes, but much smaller. You’ll typically pay a monthly connection fee ($10-30) plus charges for any grid electricity you use beyond what your solar system produces. Many customers’ bills drop from $150-250 to $10-30 monthly.
Q: Can I disconnect from the utility company?
A: Technically yes (off-grid solar), but most customers find staying connected provides better value and reliability. Grid connection acts as a giant backup battery at minimal cost and eliminates the need for oversized battery banks.
Choosing a Solar Company
Q: How do I choose the right solar installer?
A: Look for companies with:
- NABCEP-certified installers
- Strong local presence and reputation
- Transparent pricing
- Quality equipment from reputable manufacturers
- Comprehensive warranties
- Positive customer reviews
- Experience with your utility and local permitting
Get multiple quotes, compare equipment quality (not just price), and ask for customer references.
Q: What warranties should I expect?
A: Quality solar installations include:
- 25-year panel performance warranty
- 10-25 year inverter warranty
- 10-15 year battery warranty (if applicable)
- 10 year installation workmanship warranty
- 25+ year manufacturer equipment warranties
Make sure you understand who honors each warranty and what’s covered.
Q: Should I lease solar panels or buy them?
A: We recommend buying whenever possible. Ownership provides:
- Full 30% federal tax credit
- All financial benefits and savings
- Increased home value
- Simplicity when selling your home
Leases and PPAs (power purchase agreements) benefit the leasing company more than you. If you can’t buy outright, financing is typically a better choice than leasing.
Environmental Impact
Q: How much CO2 will my solar system offset?
A: An average 8kW residential system offsets about 4-5 tons of CO2 annually, equivalent to planting 100 trees each year or taking a car off the road. Over 25 years, that’s 100-125 tons of CO2 prevented from entering the atmosphere.
Q: What happens to solar panels at end of life?
A: Solar panels are 95% recyclable. As the industry matures, recycling infrastructure is expanding. Most panels outlast their 25-year warranties and continue producing electricity for decades, delaying recycling needs.
Q: Is the energy used to manufacture panels offset by their production?
A: Yes. Solar panels typically produce enough energy to offset their manufacturing energy within 1-2 years, then provide 25-30+ years of clean energy production. The energy payback is extremely favorable.
