Residential solar is where MJJ’s began — and we’ve never stopped refining it. Every system is custom-designed for your current energy needs, with built-in capacity to scale. We install to the highest standards: structurally sound, visually clean, and performance-driven. From consultation to meter changeover, we manage the entire process — so you don’t have to.
Commercial Solar Installations
Cut daytime energy costs. Increase operational control.
Solar for business just makes sense — and MJJ’s makes it seamless. We deliver custom-engineered systems that match your load profile, facility layout, and financial goals. Whether it’s a warehouse, office, or retail location, our licensed team handles every technical, compliance, and installation detail. Built for performance. Backed by service.
Solar Battery Solutions
Store your energy. Power your future.
Don’t just generate power — own it. Our battery systems let you capture excess energy and use it on your terms: at night, during blackouts, or when the grid fails. We offer scalable battery options from trusted brands, integrated professionally with your existing or new solar system.
EV Charger Installations
Charge smart. Drive clean. Power for every vehicle.
From at-home wall chargers to high-capacity commercial DC setups, we supply and install the right EV charging solution for your property. With load balancing and tailored product selection, you can maximize charging speed and efficiency — while reducing grid impact.
Licensed Electrical Services
Expert electrical work for homes, businesses, and builders.
From new builds and renovations to commercial projects and insurance claims, our licensed electricians handle it all. We work directly with you to scope, install, and deliver the exact outcome you want — safely, compliantly, and on schedule.
System Maintenance & Monitoring
Protect your investment with proactive care.
A solar system is only as good as its performance. We provide scheduled maintenance and live system monitoring to ensure optimal output and early issue detection. Whether you installed with us or another provider — we’ll keep your system running like it should.
Rural & Off-Grid Solar
Custom solar built for distance, independence, and reliability.
Rural systems demand more — and we deliver. We assess network rules, manage distance factors, and design with resilience in mind. Whether you’re grid-connected or fully off-grid, our team ensures your solar setup performs reliably under any conditions. Zero guesswork. Full support.
