Easy as ABC, whether you live in a house or an apartment. Design your own solar and storage system. Choose your size, functionality and structure here.

A

Solar PV Generation

The solar photovoltaic array produces electrical energy when exposed to sunlight, for either for feeding into an AC grid or to charge batteries.

B

Storage ESS System

Our pre-engineered power electronic and energy storage systems range from grid tied inverters to off-grid systems, to hybrid part grid part battery, EV charging and monitoring systems. All components are selected for the highest quality, reliability and endurance, are locally certified for SA -NRS097 and easy to connect to you existing 230v DB board whether single or 3 phase.

C

Shade Structures

SST has developed the PowerPort : a revolutionary solar car port modular structure which is optimized for solar yield, shade and weather, water proofing, durability, and aesthetic elements. It also provides an excellent complement to an electric vehicle for home charging using a combination of solar and grid energy sources.

Business Case example

A three bedroom Cape Town house uses approximately 40 units (KWH) per day, and pays approximately R2.50 per unit, i.e. about R100 per day or R3000 per month to the electricity utility (in this case City of Cape Town). This amount varies depending on the season, with the consumption profile, and changes in power pricing, which generally escalates at higher than CPI inflation % per annum (assuming here a 10% annual price inflation). What’s more the utility fails on occasion due to Eskom Load shedding, which becomes very inconvenient and expensive for the home owners, due to grid downtime and / or diesel backup generation.

 

 ENERGY STORAGE CASE

The electrical energy storage (ESS) component of the system, aims to keep a certain buffer of energy available for evening use and also for grid outages such as in the case of load shedding.

The current battery bank is sized at 77ah / 4KWh, full discharge.  If cycled daily at 80% discharge ie. 3.2 KWH, it is expected to last for over 13 years.  Typically, it would provide a load of 1kW for 3 hours per evening.  In the event of a grid outage the same system could provide easily provide for 3 hours of storage of 1KW essential load, or 2 hours of 1.5 kw load at 230v.  

 Note: A specific business case for the ESS investment can be made by quantifying the cost of not having energy or the cost of a diesel generator investment, maintenance and fuel.

SOLAR POWER

Upon installing an 4.4KW Sun Ship PowerPort, the house is supplied with 20 units (KWH) from solar panels, which is 50% of the average daily requirement. For every unit produced by the PowerPort the house reduces purchasing the same number of units from the utility. .

In this case the numbers as follows: 

Monthly cost reduced = R2.50 x600 units = R1500

Annual cost reduced = R2.50 x7200 units = R18000

15 year costs reduced = over R570 000.

 If we assume a capex outlay of R190 000, the payback period is 7 years, and IRR is 14%
