1) Solar tracker with economical inverter system

The Challenge: Maximize solar power output from array at minimal balance of system costs.

Solar Array: 0.8 kW
Sun Tracker: Wattsun single axis with seasonal tilt adjustment as a custom add-on.
Battery: None—strictly grid-connected.
Inverter system: Dual European 12V DC to 110 V AC inverters imported exclusively by us to minimize startup costs and maximize system modularity.

2) Solar and Wind hybrid, grid-connected.

The Challenge: Make a significant contribution to year-round electrical consumption with hybrid solar/wind system.

Minimise impact of solar modules on the aesthetics of the building.
Solar Array: 0.6 kW, Thin-film CIS solar modules, fixed to dormer roof.
Wind Turbine: 1 kW Bergey XL.1 (up to 1.2 kW peak power) on 64 ft guyed tower
Battery: Minimum size to run the inverter—no storage capacity; backup power possible in future expansion.
Inverter System: 2.5 kW, 24V DC – 110 V AC

3) Solar, grid-connected, backup power.

The Challenge: Maximise garage roof surface area for solar output and provide backup battery capacity for essential household loads.

Solar Array: 2.6 kW, monocrystalline, mounted on pitched roof.
Battery: 20 kWh backup capacity, flooded deep cycle.
Inverter System: 4.0 kW, 48 V DC – 110 V AC with 120/240 step-up transformer for deep well pump. The solar array contributes 1/3 of the house’s electricity and keeps the battery charged during an extended power outage, allowing longer backup time.

4) Off-grid home (under construction).

The Challenge: Integrate solar modules into the design of the building to maximize their benefit by using them as a window canopy. Integrate wind turbine into deck on building rooftop.

Solar Array: 1.2 kW, polycrystalline, mounted on window shading canopy bracket.
Wind Turbine: 1 kW, roof mounted with noise-damping bracket.
Battery: 38 kWh flooded deep cycle 2 V cells.
Inverter: 4.0 kW 24 V DC – 110 V AC
Other: Dump load to feed excess electricity into a water heating element.
Other: LED and DC lighting fixtures.

5) Larger scale grid-connected home with custom manual tilt adjustment.

The Challenge: Provide customer with a means of seasonal tilt adjustment to maximize array output; conceal the solar array below the roof parapet.

Solar Array 1: 2.2 kW monocrystalline mounted to sloped roof surface.
Solar Array 2: 3.3 kW monocrystalline mounted on manual variable tilt apparatus.
Solar Array 3: 2.8 kW monocrystalline mounted on manual variable tilt apparatus.
Battery: N/A
Inverter 1, 2: 1-5 kW modular grid-connected inverter, 190 V DC – 240 V AC.
Inverter 3: 3 kW grid-connected inverter, 190 V DC – 240 V AC.
Inverter Remote: Provided in all three cases to track real-time and accumulated output, greenhouse gas displacement, and other parameters.
