At Johnstone Electrical & Sunvalley Solar, we pride ourselves on delivering top-notch solar energy solutions tailored to our clients’ specific needs. Recently, we completed a high-quality installation featuring some of the most advanced products available in the solar industry: Enphase microinverters, WINAICO solar panels, and the 10kWh sonnen Evo AC-coupled battery.

Why Enphase Microinverters?

For this project, the client had some shading issues due to nearby trees. In cases like this, Enphase microinverters are the only sensible option. Unlike traditional string inverters, Enphase microinverters optimize each solar panel individually, ensuring that shading on one panel doesn’t drag down the performance of the entire system. This maximizes energy production, making the most out of available sunlight, even in less-than-ideal conditions.

The Power of Winaico Solar Panels

We paired the Enphase microinverters with Winaico’s bi-facial and half-cut solar cells. These panels are designed to capture as much solar energy as possible, significantly boosting overall system efficiency. Winaico’s advanced technology allows their panels to absorb light from both sides, increasing energy production, especially in diffuse light conditions like cloudy days or shaded areas.

Reliable Energy Storage with Sonnen Evo Battery

To complement this robust setup, we installed a 10kWh sonnen Evo AC-coupled battery. This battery is not only highly efficient but also reliable in critical situations. In the event of a blackout, the sonnen Evo can output up to 5kW of energy, keeping essential appliances running. Additionally, it ensures that the Enphase microinverters stay online during daylight hours, so they can continue to generate power and recharge the battery.

Why Choose Us?

Whether you’re dealing with shading issues, need a reliable energy storage solution, or simply want the most efficient solar panels on the market, we have the expertise to design and install a system that meets your needs. Our team is dedicated to using only the best products in the industry to ensure that your investment in solar energy is one that will pay off for years to come.
