Personal attention.
I’m Doug Mycko, owner of SolarMan Consulting. I help people put together off-grid solar systems, choose equipment and work through problems with the systems they already own.
Good system planning starts with a conversation: what you need to power, how you use it and what you want your system to do. From there, we can work toward a practical equipment plan.
SolarMan began in 1984. I joined the company in 2006 and became its owner in 2016. Today I focus on equipment, system design, troubleshooting and helping customers get more from their off-grid systems.

Can you help with an existing OutBack system?
Yes. Doug helps with equipment identification, replacement parts, settings and troubleshooting. Have your inverter and charge-controller model numbers ready, along with battery information and any fault messages. The battery-testing guide explains useful OutBack log information.
Where do I start when sizing an off-grid system?
Start with your location, daily electrical loads and overnight energy needs. Use the whole-system sizing guide for an initial estimate, then discuss the equipment and site details with Doug before purchasing.
Do you sell equipment and DIY solar kits?
Yes. Explore the equipment catalog and DIY solar kits. Doug can help match panels, batteries, inverters and supporting components to your project. Contact him to confirm pricing and availability.
Can you help me determine whether my batteries need replacing?
Yes. Begin with the lead-acid and lithium battery-testing guide, then share your model numbers, charging history and symptoms with Doug. Testing helps separate battery wear from charging, connection and settings problems.
Do you deliver on the Big Island or ship to other islands?
Big Island delivery and inter-island equipment shipping are available. See the shipping policy and contact Doug to confirm arrangements for your location and order.
