Residential Solar PV Solutions..

Solarway are a specialist Residential Solar PV EPC (Engineering, Procurement & Construction) company.

Residential solutions can be either Grid-Tied (no batteries), or Grid-Interactive or Off-Grid (which use battery banks) type systems. Solutions are designed to meet the Building usage patterns and/or available Budget. Savings Guaranteed!!

Power.SURE Range

The Power SURE systems use Energy Storage (Batt Banks).

Power SURE systems give you power ASSURANCE (i.e. Guaranteed Power when you need it).

Power SURE systems offer the following benefits:

  • Battery Backup.

  • Self-Consumption Energy Usage.

  • Self-Consumption Energy Usage + Battery Backup.

  • Energy Cost Savings.

  • Power during Utility Failure (e.g. Load Shedding).

  • Sell Excess energy back to the Utility (Nett Metering) .

  • Energy Independence .

These systems can be configured to achieve all or most of the above benefits, based on the technology chosen or your specific requirement.

These systems are usually configured to do the following:

  • Store Solar Energy during the Day-Time  +

  • Use stored Solar Energy during the night or during Peak (expensive) periods  +

  • Leave a backup reserve in the batt bank (in case of grid failure / load-shedding).

CONFIGURATION:     Grid-Interactive / Self-Consumption / Off-Grid

TECHNOLOGY:          Tier-One Manufacturers Only.

Power.SAVE Range

The Power SAVE systems are designed to SAVE you money on your electricity bill.

These systems do NOT use Battery Banks.

They produce FREE electricity during the day and inject this power directly into the Homes electrical system.

The Nett effect is a reduction in your Utility Bill.

Excess power can be sold back to the Utility (if permission is granted by your SP).

Return on Investment can be less than 3 years with a 20 year IRR of up to 45%.

Low Risk ~  High Return Investment

It is advised the Home Owner try and maximise their day-time load, by running as many loads during the day as possible, incl:

  • Swimming Pool Pump

  • Laundry: Washing Machines, Ironing, Tumble Dryer..

  • Dish Washers

  • Geysers/Heat Pumps

  • Under Floor Heating

  • etc


TECHNOLOGY:          Tier-One Manufacturers Only.

Grid-Tied Systems

Solar PV (photovoltaic) roof-top, Grid-Tied systems are the most common type of solar PV installation around the world (93% of all PV systems are grid-tied). These systems do not store their energy in battery banks.

Electricity produced during the daytime by the sun is either used in the dwelling/building or directed back into the electricity grid, this puts your power usage into credit (i.e. Nett-Zero Energy Building).

These Roof-Top systems can either Reverse the utility meter or are designed for close to 100% Self-Consumption usage.

Grid-Tied systems effectivley reduce or eliminate the KWh portion of the electricity bill, thereby reducing or eliminating this cost.

The initial cost in investing in this technology is typically offset within a few years and the long term savings (30+ years) can be significant:

ROI:  3 yrs to 7 yrs | IRR: 15% to 70%

Grid-Interactive Systems​

Grid-interactive PV systems give users more choices and greater flexibility, while increasing the level of reliability in deployments.

A Grid-interactive system can bee seen as a combination of an Off-Grid system (with a battery bank) and a grid-tied system (uses the grid as backup and/or sell excess energy into the grid i.e. Nett-Metering).

The battery bank can typically be smaller than what is required in an off-grid system; sized to drive just the essential load(s) during a power-outage, with the grid as a reliable backup energy source for bad weather days.

Grid-interactive systems are often more affordable than off-grid systems and these systems are scalable, meaning the pv system can be expanded over time (i.e. start smaller ~ than grow the system size later on).  These systems are usually very good medium to long term investments, shielding the system owner from the ever increasing electricity costs.

Off-Grid Systems

Off-grid (or “stand-alone”) PV systems are very different to batteryless grid-tied systems.

Without the grid as a supplemental electricity source, a PV system’s sizing is critical.

Off-grid systems require their owners’ participation—this means living within the original design’s energy budget, planning for future growth, and having a backup energy source for times of high energy usage or low solar production.

All maintenance and equipment servicing is critical to the effectiveness and durability of the system.

An Off-grid system must always have a backup energy source. This backup source would typically be used during bad weather when the irradiance level from the sun is not sufficient to supply the load or charge the batteries, or both.

Typical Off-grid applications include: schools, lodges, holiday homes, clinics, telecom stations, etc.
