Tips for Selecting the Best 3 kW Solar System

To help you choose the right rooftop solar system for your home, here are some tips to consider.

1. Choose a Provider Who Conducts a Thorough Roof Survey

Not all installers carry out detailed roof inspections, which can result in poorly aligned panels or sloppy installations. To avoid this, go for a company that employs technology for shadow analysis throughout the year, pinpointing any obstructions that could affect your system.

A proper roof assessment should include evaluating available space and estimating your energy needs. This approach ensures optimal system performance and minimises risks such as hotspots, reduced power output, or even fire hazards.

2. Opt for a Vendor Who Offers Tailored Engineering Solutions

A generic installation may not address your home’s unique requirements. Many local solar companies overlook the structural aspects of your roof, leading to less efficient setups. Choose a provider that uses precise engineering to design your solar solution, ensuring it fits your roof’s specifications for safe and efficient energy production, leading to a higher return on investment.

3. Look for a Vendor That Guarantees Savings

Research by CEEW and PV Diagnostics shows that over half of solar systems underperform in the first year, with a further 30% decrease in the second year. Secure your investment by choosing a vendor that guarantees savings and provides compensation for any power generation shortfalls. This ensures you get the value expected from your solar installation.

4. Ensure the Provider Offers Certified, Storm-Proof Structures

With extreme weather events becoming more frequent, your solar system must be built to withstand tough conditions. Choose a vendor offering cyclone-resistant and certified structures designed to endure high winds. This ensures your solar installation remains secure regardless of the weather.

5. Prioritize Ongoing Maintenance and Support

Solar systems need regular upkeep to operate efficiently. Choose a provider offering comprehensive maintenance services to keep your system running smoothly for years. Maintenance packages should cover cleaning, inspections, and system optimization.

6. Verify the Availability of Financing Options

The initial cost of solar installation can be high. Select a vendor that provides reliable financing options, making it easier to manage the upfront expense. Verified financing arrangements allow for a seamless transition to solar energy, alleviating the financial burden.
