Some key advantages of hybrid solar systems supplied and installed by Specialized Solar Systems:

  • If the power generated by PV solar arrays is inadequate to supply daytime loads as well as charge your batteries, the system can recharge your batteries from the grid when a generally lower off-peak electricity rate is applied.
  • When electricity usage goes above a certain level nationally, the grid supply may charge you a higher rate for the increased level of demand. Hybrid solar systems can provide ‘peak lopping’ where some of the stored power can be drawn from the batteries to help balance power usage.
  •  If your grid connection does not have the capacity to supply the required load, a hybrid solar system will supplement any extra power. This may allow you to avoid a costly mains upgrade for your property.

Hybrid solar systems empower you with energy security and self-sufficiency, lock in your future cost of electricity, control when you use your solar power, and provide an uninterrupted power supply.

The system is designed solely for the farms’ use to lower electricity expenditure during the day and night, and to overcome the Eskom rising tariffs charges saving money in the more economical time of use periods.
It features a 90kWp solar array which provides the energy to reduce the farm daytime power costs (running of irrigation pumps etc) and to charge the batteries for use during the late afternoon milking of the cows. The solar array will produce on average 410kWh per day.

The solar array is coupled with 3 x 27kVA Fronius 3-phase commercial inverters. The AC coupled is also connected to 6 x 15kVA Victron Quatro inverters-chargers used to charge the storage. The storage capacity is delivered by 2 x 80/64 Freedom Won batteries giving a total of 128kWh of useable energy.

The use of the 6 x 15kVA Victron inverter/chargers creates scheduled charging of the batteries during the low tariff period between 23h00 until 04h00. The tariff during this time is low (90c/kWhr) and the batteries are then discharged during the early morning milking when the tariff is very high (R 4.20/kWhr).

A grid-tied solar-powered electrical system is also known as tied to the grid, or grid-tie system and is a semi-autonomous electrical generation or grid energy storage system.

Background: Specialized Solar Systems Grid-Tie solar-powered system

How does a grid-tie solar power system work?

A grid-connected inverter converts DC electricity produced by the solar panels into AC electricity, which can then be used by the property/household. If a grid connect system is producing more power than is being consumed, the surplus is fed into the mains power grid (if your municipality allows). Alternatively, when there is no solar panel generation or if inadequate, the inverter will allow grid-power to compensation.

Advantages of Grid-Tie Systems

  • A grid-connection will allow you to save more money with solar panels through better efficiency rates and lower equipment and installation costs. Batteries and other stand-alone equipment are required for a fully functional off-grid solar system. This adds to costs as well as maintenance. Grid-tied solar systems are generally much cheaper and also simpler to install.
  • Homeowners can also put excess electricity back onto the utility grid instead of storing it themselves with batteries. This is done with special meters (if allowed in your area).

The utility grid is a virtual battery
Electricity should be used as it is generated. However, it can be temporarily stored as other forms of energy (e.g. chemical energy in batteries).  Energy storage typically comes with significant costs.

The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity (and more money) goes to waste with conventional battery systems.

Additional perks of being grid-tied include access to backup power from the utility grid in case extra power is required or if your solar system stops generating electricity for any reason.  At the same time, you also help to mitigate the utility’s peak load.

Customers should please contact Specialized Solar Systems for more information on purchasing a Grid-Tied solar system and for expert advice when choosing the right solar power system solution for your electrical energy needs.

Method of Integrating Solar into the National Network

Written by Arno Menkveld on . Posted in Agriculture & rural solar energy solutions, Commercial solar solutions.

Throughout Africa, a central energy distribution method is typical, supplying energy over long distances to networks that are metered and paid for by consumers. The energy business model calculates the amount of energy generated, transmitted, and sold to formulate a profitable or non-profitable business. In this calculation, the loss of energy through transmission, stolen energy, and unpaid energy becomes the Achilles heel of an archaic business model.
