Introduction

Solar panels allow homeowners to generate their own clean electricity from sunlight. With solar electricity costs dropping and efficiency rising over the past decade, solar panels are an increasingly beneficial investment. This guide provides unbiased solar panel reviews and recommendations to help you choose the ideal solar system based on your home’s needs and budget. We cover all the key factors – top brands, costs, tax credits, installers, warranties, and maintenance considerations.

Reviews of Top Solar Panel Brands

The solar panel brand you choose significantly impacts system performance and reliability. Here are reviews of leading manufacturers:

Warranty: 25 year power warranty. Energy production guarantee.

Cost: Around $1.75-$2.25 per watt. Tesla ecosystem may increase overall system cost.

Solar Panel Costs

Solar panel costs are measured based on the price per watt of installed solar capacity. The average residential solar panel system ranges from $2.50 to $3.50 per watt. At approximately $3 per watt, a typical 6 kW system would cost around $18,000 before incentives. Key factors affecting solar panel system pricing include:

  • Brand and panel efficiency – Premium brands cost more but generate more energy.
  • Panel warranty – Longer warranties (25+ yrs) mean higher quality and cost.
  • Installer experience – More experienced solar companies often charge more.
  • Roof type/condition – Tile, shingle, flat roof installations vary. Roof repairs may add cost.
  • Customization – Complex designs, premium components increase price.
  • Location – Solar costs vary by city based on labor costs, permits, incentives.

Solar Incentives and Savings

Various solar incentives and savings benefits help offset the installation costs and maximize your return on investment:

  • Federal Tax Credit – 26% of installed costs through 2022. Reduces to 22% in 2023 then 0% in 2024. Apply when filing taxes.
  • State/local rebates – Additional rebates based on location. Check Database of State Incentives for Renewables & Efficiency for your area.
  • Net metering – Utility credits excess solar energy fed back into the grid. Important for maximizing solar savings.
  • Electricity bill savings – Solar replaces the need to purchase grid electricity during daytime. Utility rates impact savings amount.
  • 30% depreciation – Business owners can claim solar as a tax depreciation asset to reduce taxable income.

With incentives applied, the payback period for solar panels ranges from 4-8 years typically. Ongoing electricity cost savings continue to provide return over the 25+ year lifespan.

Choosing a Solar Installer

Selecting the right installation company is just as important as the brand of solar panels chosen. Key factors to evaluate solar installers on include:

  • Experience – 5+ years installing solar maximizes expertise. Verify licenses and training.
  • Reviews – Check third-party review sites for ratings and feedback from past customers.
  • Warranty – At least 10 years on labor/workmanship. Longer warranties (20-25 years) provide more protection.
  • Roof penetration warranty – Protection from any leaks or water damage caused.
  • Posted prices – Upfront pricing by the watt shows transparency. Get full breakdown.
  • Maintenance services – Some offer panel cleaning, inverter checks as added value.
  • Responsiveness – Speed at returning calls/inquiries demonstrates dedication.

Vet potential installers thoroughly and compare multiple bids. Have an attorney review any contracts before signing.

Pros and Cons of Solar Panels

Solar power provides many benefits but also some downsides to consider:

Pros:

  • Lower electricity bills
  • Increased home resale value
  • 30% federal tax credit through 2022
  • Energy production for decades
  • Reduce environmental impact
  • Backup power generation with batteries

Cons:

  • High upfront installation cost
  • Roof must be sun-exposed most of day
  • Old roofs may need replacement
  • Effectiveness varies seasonally
  • Higher maintenance than grid electricity
  • 10-25+ year investment timeline

Understanding both the advantages and compromises of solar helps set proper expectations. Solar makes sense for eco-minded homeowners planning to stay long-term.

Solar Maintenance

While solar systems require minimal maintenance compared to other home systems, occasional upkeep is recommended:

  • Panel cleaning – Clean panels 2-4 times per year for optimal production, especially in dry climates prone to dust buildup.
  • Inverter checks – Make sure inverters are functioning properly each year. Test display panel and fans.
  • Wire inspections – Inspect cabling for any damage, cracks, loose connections that could cause issues.
  • Production monitoring – Verify solar production data monthly and check for any decreases that could indicate problems.
  • Tree/shading control – Trim any trees that may overhang and shade panels during peak sun hours.
  • Snow removal – Gently clear snow off panels in winter, allowing some melting between removal.

Some solar installers offer maintenance packages and warranties to handle upkeep. DIY maintenance can save costs for minor tasks.

Solar Batteries

Adding solar batteries allows energy storage for use when the sun isn’t shining. Key factors regarding batteries include:

  • Battery options – Lithium-ion batteries like Tesla Powerwall offer compact storage and 10+ year lifespan. Cost is $10,000-$15,000 installed.
  • Applications – Batteries provide backup power during grid outages. They allow solar power usage at night.
  • Costs – Battery systems are still an expensive additional investment, ranging from $7,000-$30,000 depending on capacity.
  • Incentives – Some states offer rebates on battery installations. The federal tax credit applies to batteries too.

Unless you need backup power or want to maximize self-consumption of solar energy, batteries may not provide sufficient return on investment yet for most homeowners. The economics continue to become more favorable over time.
