About LCP Solar

What We Do

LCP Solar, in accordance with legislation, is a registered electrical contractor.

We make no secret of the fact that LCP Solar does not install “cheap and nasty” and off-the-shelf solutions. We undertake a proper analysis of our client’s requirements and design bespoke systems to their needs.

Our design considerations and installations are according to or exceed national standards.

Installation workmanship is warranted for 5 years – that says a lot.

NRS Documents

Earthing and bonding cables

  • Earthing and bonding cables shall have a minimum cross-sectional area of 6mm2
  • Where positive and negative live conductors exceed 6mm2, the earthing and bonding conductors shall have a minimum cross-sectional size conductor. equal to the positive and negative live conductors.
    This means – PV cables are 4mm2, 6mm2, 10mm2 or thicker. One may not install earthing conductors less than 6mm2; Installations with 1.5mm2, 2.5mm2  or 4mm2  earthing conductors are illegal.

PV Array system

The voltage rating of the PV array system shall be the maximum open-circuit array voltage at the lowest operating temperature.
This means – let’s say a charge controller has a maximum input voltage of 450 volts and a PV module is say 50 volts. This voltage is listed at STC which is 25°C  voltage increase as it gets colder.
Thus, installing 9 PV modules @ 50 volts which is equal to 450 volts would not be good practice.

Verification and Testing

Every user or lessor of an EGI shall have a valid CoC for every such installation. A CoC shall only be valid when it is accompanied by a test report in the format as specified in this document and SANS 10142-1.
This means – That, apart from the specific requirements in SANS 10142-1, when you install a PV system you are required BY LAW to obtain a NEW CoC for the part of the Installation affected by the changes.

Efficient East-West Orientated PV Systems with one MPP Tracker

ABSTRACT: A willingness to install east-west orientated photovoltaic (PV) systems has lacked in the past. Nowadays, however, interest in installing PV systems on east-west roofs is steadily increasing. Although south orientated systems are better, east-west orientated PV systems can also generate substantial earnings. Moreover, due to the sharp drop in module prices, increased demand for east-west systems are expected for the future. From the perspective of grid operators, east-west orientated PV systems are preferable to south orientated ones, as the energy is fed in more evenly throughout the day, therefore reducing power peaks thus relieving the grid. Up to now, it was assumed that east-west orientated PV systems require separate inverters for each orientation, or at least one inverter with multiple MPP Trackers (Maximum PowerPoint), to avoid mismatching losses. This paper will show an analysis of east-west orientated PV systems connected to one MPP Tracker and demonstrate the high performance of such systems.
