What to Consider When Choosing Solar Companies in Surrey

Key Factors to Consider When Choosing a Solar Company

1. Accreditations and Certifications

Not all solar companies are created equal. To ensure quality and compliance, look for accreditations from recognised industry bodies, such as:

• Microgeneration Certification Scheme (MCS) – Guarantees the company meets industry standards.
• Renewable Energy Consumer Code (RECC) – Ensures ethical sales and service practices.
• NICEIC or NAPIT Certification – Indicates qualified electricians are handling your installation.
• Solar Trade Association (STA) Membership – Demonstrates commitment to industry best practices.

A certified company not only delivers high-quality installations but also ensures eligibility for government incentives like the Smart Export Guarantee (SEG), which pays you for excess energy exported back to the grid.

2. Experience and Reputation

Opt for companies with a proven track record in residential and commercial solar panel installation in Surrey. Check:

• How long they have been in business.
• Customer reviews on platforms like Trustpilot and Google.
• Case studies or testimonials showcasing successful installations.
• Their portfolio of previous projects, particularly in properties similar to yours.

A reputable company should be able to provide references from past customers who can vouch for their work.

3. Types of Solar Panels and Inverters Offered

The quality of your solar system depends on the components used. Ask about:

• Solar panel efficiency – Premium brands like SunPower, LG, or Panasonic offer higher efficiency and durability.
• Inverter technology – Consider whether they provide string inverters or microinverters, as microinverters optimise energy output per panel and increase system reliability.
• Battery storage options – If you want to store excess energy, ensure they offer reliable solar battery storage solutions in Surrey, such as Tesla Powerwall or LG Chem.
• Solar mounting systems – Ensure they use durable, corrosion-resistant mounts for longevity.

4. Pricing and Financing Options

While affordability is important, the cheapest option is not always the best. Obtain at least three quotes and compare:

• The cost per kilowatt (kW) of installed capacity.
• Whether pricing includes installation, permits, and aftercare services.
• Availability of financing options like solar loans, leasing, or power purchase agreements (PPAs).
• Hidden costs – Make sure quotes are transparent with no unexpected charges.

Some companies offer zero-deposit solar panel finance in Surrey, making it easier to spread the cost. Others provide government-backed incentives to make solar more accessible.

5. Warranties and Aftercare Services

A reputable solar installer provides strong warranties, including:

• Panel performance warranty (typically 25 years) – Guarantees energy output over time.
• Product warranty (10-15 years) – Covers manufacturing defects.
• Workmanship warranty (5-10 years) – Protects against installation issues.

Additionally, ask about maintenance packages and customer support availability. Regular maintenance helps prevent issues and ensures optimal performance over time.

6. Energy Savings and Return on Investment (ROI)

Before committing, request an estimated payback period. A quality installer should provide:

• A detailed energy savings report based on your household’s electricity usage.
• Information on how much you can earn through SEG payments.
• A breakdown of expected ROI over time.

A well-installed solar system can pay for itself in 6-10 years, with financial benefits lasting decades beyond that.

7. Local Knowledge and Expertise

Choosing a local solar installer in Surrey has advantages:

• Better understanding of Surrey’s building regulations and planning permissions.
• Quicker response times for aftercare services.
• Personalised support tailored to your area’s solar potential.

Local companies are also more likely to be familiar with specific regional factors, such as shading issues or roof types common in Surrey properties.

8. Solar Battery Storage Options

For homeowners looking to maximise self-sufficiency, solar battery storage in Surrey is a valuable addition. Ask your installer about:

• Compatibility with existing solar panels.
• Storage capacity and expected lifespan.
• Smart energy management features.
• Savings potential from stored solar power usage during peak hours.

Batteries allow you to store excess energy generated during the day for use at night, increasing overall efficiency.

Red Flags to Watch Out For

When selecting a solar company, beware of:

• Unrealistic energy savings claims – If it sounds too good to be true, it probably is.
• High-pressure sales tactics – A reliable company provides time to consider your options.
• Lack of physical address – Ensure they have a verifiable business location.
• Poor online reviews or unresolved complaints – Look for transparency in dealing with customer issues.

If you are considering solar panel installation in Surrey, take time to research and compare providers. A reputable company should offer transparency, expertise, and high-quality products. Investing in solar is a long-term commitment, so making the right choice now ensures you reap the benefits for decades.
