Should I install an off-grid system?

Off-grid solar means that you are completely disconnected from the HELCO grid. All of the energy used in the household will be coming from sunlight. Off-grid systems are perfect for those who live far from power lines, want to minimize their environmental impact, or simply want to be energy-independent. When the grid goes down - due to a storm, downed power line, or technical issues - your off-grid system still has power. Typically, a generator is used when extra power is needed.

​"Conversations with Roland to determine the right system for us were very clear and concise. Roland’s patience and professionalism throughout the process was a pillar of confidence for my wife and I. The installation crew was amazing. They were polite, knowledgeable and patient. They worked hard and fast and left the site just like they found it. The turn-key setup was exactly what we were hoping for. We have a lot to learn about our new system and plan on diving straight into it. However, being able to simply walk in and flip on the lights was really satisfying.

How it works

1.

Solar panels turn sunlight into clean DC electricity.

2.

The inverter charges the battery pack with DC current...

3.

...While the inverter turns DC current into usable AC electricity.

4.

This electricity goes straight to your circuit breaker, powering your home.

Off-Grid, then and today

​In 1976, Renewable Energy Services (RES) founder Peter Shackelford built his own off-grid power system with a wind turbine mounted on a tall Eucalyptus tree and four, 6-volt batteries. Off-grid energy technology has come a long way since then, and now is often more reliable and more affordable than the utility. We combine high-performance solar modules with long-lasting, maintenance-free batteries to provide Hawaii's safest, most dependable off-grid power systems.
