No, the total price we sent is for the individual components required to supply the power you need. However, we clearly indicate installation charges when the total price includes installation.

Yes, definitely. You can start with 50% batteries and get the remaining when you are ready. Also yes during the day when the sun is out, the panels will charge the batteries but that also depends on the priority configuration of your inverter (i.e either to supply the power from the panels directly to all your load and charge the battery with excess power or charge the batteries as first priority and supply the remaining power to your load. This is the same for the grid supply ( ECG and generator ) you can configure it to suit your requirement. However, under normal circumstances, your understanding should hold positive. We do not recommend charging the batteries with generators as they have the potential to damage your inverter.
The main difference between the two batteries is the build technology and the choice of electrolyte being used. In terms of performance, they are both great with almost identical performance grade. The AGM excels at delivering high bursts of current whiles the Gel excels at slower discharge rate. The flexibility of AGM makes it very easy to be used anywhere; Gel batteries have a longer life span compared AGM if it is maintained properly.
PV modules are multifunctional building components which, besides generating electricity, can fulfil many other functions such as shading systems, light filtering etc.
When speaking about BIPV, the PV modules are fully integrated into the building, since they form an integral part of the building mostly to serve as an auxiliary source of power to reduce the cost involved in using traditional building materials. The advantage of BIPV is that, eventually the energy generated will offset the cost involved.
Generally, a Building Integrated PV (BIPV) System is designed to serve more than one function. The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labour that would normally be used to construct the part of the building that the BIPV modules replace.
There are no limits for installing PV systems when good exposure is achievable. Beyond roofs, some of the most common suitable locations are ground mounting, sheds, facades etc.
PV systems constitute a reasonable alternative for construction materials to be considered by architects.
In order to install Photovoltaic systems, knowledge about electricity is required, especially about dimensioning and protection. You also need to understand the fundamental working principles of each component of the PV system and how they work together.
The first step is to find out the customer’s wishes. This has to match the existing space – shadow-free roof. You should also take notice of all appliance to be used on the system and factor in the efficiency of the inverters and solar panels.
The yearly value of kWh that a system will produce depends on the system size (in kWp), design, the irradiation.
Standard mono-crystalline modules are relatively light, around 10 to 15 kg per square metre. A PV system’s load will be distributed evenly to reduce stress on the building.
A PV system needs daylight to work but not direct sunlight. Although direct sunlight improves efficiency.
PV is a renewable energy source that produces electricity. Electricity can be used for all home appliances and lighting. Moreover, solar is more cost efficient and robust with less moving parts.
The best indicator for sizing a PV system is your historical electrical usage or the number of kilowatt-hours (kWh). We can also do a survey and design the system to meet your power needs.
PV systems, like every other product, do require energy during the manufacturing process. However, PV systems pay back this energy
Batteries are only essential if power needs to be ‘stored’ in case of a utility outage.
The cost of PV technology has dropped dramatically in the past ten years and, thanks to government incentives or subsidies…
PV is a technology that generates electricity, not heat. Therefore, the existing heating system remains unchanged. However, in order to reduce the cost, we advise purchasing a standalone solar water heater.
PDS has committed to bringing back this system, so that excess power can be sold back to the grid.
In most cases, the PV modules don’t need to be clean. We advise cleaning the PV modules once in a while to prevent thick layer of dust forming on it.
If your home has a roof with some shadow-free space, a PV system can generate electricity for your consumption. With…
PV modules are most often encapsulated in two layers of tempered low iron glass or between glass and Tedlar. This makes it very fragile to walk on, you are therefore advised to avoid walking on them.
This is not necessary for an off-grid and a hybrid system since they are mostly independent of the grid. You may need to contact your supplier to secure a Net meter for a grid-tie system.
