What do customers and industry experts say about the quality of their installations and customer service? Do they have consistently positive reviews and feedback?

Are they approved installers under schemes like MCS, ISO, RECC etc.? Do their technicians hold key qualifications and training?

Do they offer the full spectrum of solar options? Including panels, inverters, batteries, EV charging etc.? Or more limited in their products and services?

Do they provide strong warranties on products, workmanship, and performance?

Are they fully insured for installations and operate safely?

Pricing / Value
How do their [pricing and financing](/solar-advice/solar-panel-financing) options compare? Do they offer competitive rates and packages given their experience and reputation?

Availability / Coverage
Do they serve customers nationwide or only regionally? How widely available are their services?

Quality / Expertise

How To Choose An Installer

How to Choose a Solar Panel Installer

Choosing the right solar panel installer is crucial for a smooth process and long-term returns from your solar investment. Here are some tips for selecting the best installer:

Research Experience and Qualifications
Look for an established company with several years of proven experience. Confirm they have licensed electricians and technicians certified by the [Microgeneration Certification Scheme](/solar-advice/mcs-certification) (MCS).

Get Multiple Quotes to Compare Costs
Contact 3-5 local installers to provide site assessments and written [quotes for your solar system](/solar-advice/solar-panel-quotes). Compare pricing, [financing options](/solar-advice/solar-panel-financing), timeframes and projected output.

Read Reviews of Recent Installations
Check for reviews of the installer's recent work on sites like Trustpilot and Google. Look for consistently positive feedback on service, quality, and system performance.

Consider Additional Services Offered
Some installers provide expanded options like EV chargers, battery storage, monitoring systems etc. Determine what bundled solutions fit your needs.

Compare Warranties
Aim for at least 10 years coverage on labour and equipment. Quality installers often provide 25-year warranties on [new solar panels](/solar-advice/home-solar-panels-guide).

Assess Responsiveness and Communication
Note the installer's communication style from your initial outreach onwards. Responsive installers demonstrate attention to customers.

Verify Insurance Coverage
Confirm the installer carries general liability insurance as well as workers' compensation for employees.

Taking the time to carefully evaluate multiple installers will help you find the right instaler for you. Keep in mind cost shouldn't be the only factor. Experience, qualifications, responsiveness and warranty coverage also impact long-term value.

Who Can Install Solar Panels?

Who Can Install Solar Panels?

Installing solar panels requires specialised skills and training to ensure the system is properly set up, connected, and functions safely and efficiently.

In the UK, it is recommended to use a solar installer who is certified under the Microgeneration Certification Scheme (MCS). The MCS certifies solar installers have received accredited training on the design, installation, set-up, and maintenance of solar photovoltaic (PV) systems.

MCS certified installers include:

Licensed Electricians
Electricians experienced in solar energy systems are qualified to undertake the electrical work involved in the installation, including connecting the [solar panel kit](/solar-advice/solar-panel-financing) to your home's electrical system.

Accredited Solar Technicians
Those who have completed advanced solar training programmes and exams can receive [MCS certification](/solar-advice/mcs-certification) for solar PV installation. This ensures they are experts on solar systems.

Renewable Energy Companies
Many companies specialising in renewable energy technologies like solar have in-house installers on staff who hold MCS certification for solar PV.

Other experienced professionals like roofers may also take advanced solar training to gain qualifications for rooftop installations.

However, only MCS certified individuals have validated expertise to correctly and safely install solar panels and connect them to your home's electrical system.

Using properly trained and certified solar installers ensures your solar panel system meets all regulations and standards. It also guarantees high-quality workmanship so your solar investment functions optimally for years to come.

How To Find iunstallers near me

How to Find Solar Panel Installers Near Me

Looking to go solar? Here are some useful tips for finding qualified solar panel installers near you:

Use Online Directories
Check solar industry directories like the Solar Energy UK or Renewable Energy Consumer Code to find certified local installers. Search by your postcode to filter for your area.

Ask for Referrals
Talk to friends, family or neighbours who have solar installed and ask who they used and would recommend. Referrals can help find reputable local options.

Search Regional Keywords
Use Google to search phrases like "solar panel installers near me" or "solar companies near me". Look at reviews and credentials.

Check Social Media
Many solar installers advertise their services on Facebook and other platforms. You can search by location and often message them directly.

Compare Quotes
Contact 3-5 installers operating locally to provide on-site assessments and detailed quotes for your property. Compare costs and services.

Look for Local Certifications
In addition to MCS certification, see if installers have additional local licensing showing they are permitted in your council area.

Attend Industry Events
Local solar fairs and workshops are great for directly engaging potential installers and learning about those active in your area.

Finding certified solar professionals nearby ensures full compliance, quality workmanship and post-installation support. Take time to research options and don't just go with the first company you find.

What to Avoid When Choosing an Installer

There are certain warning signs and mistakes to avoid when evaluating potential solar installers.

Lack of Licensing
Steer clear of any installer that lacks proper licensing, accreditations like MCS certification, and liability insurance. This signals a potential scam or safety issues.

Avoid any high-pressure sales tactics or claims that seem exaggerated or too good to be true. Reputable installers focus on assessing your needs.

Too Cheap or Too Expensive
Be wary if quotes seem abnormally low or unreasonably high compared to other installers. Competitive fair pricing is ideal.

Only Looking at Pricing
Don't make your decision based on cost alone. Factors like experience, warranty, reviews and quality also impact value.

Relying Too Much on Review Sites
Online reviews provide helpful insight but may not reflect typical experiences. Take them with a grain of salt.

Forgetting to Use a Checklist
Have a checklist ready to compare each installer across important criteria like licensing, experience, services, warranty etc.

If They Want to Sell You Extras
Avoid feeling pressured to buy additional products or services beyond your needs. Stick to your budget.

Doing your due diligence avoids pitfalls and helps find the best home solar installer for a smooth, hassle-free solar installation.
