Design

A power audit that was performed after the first contact with the client determined the amount of grid power available to the client, the appliances that were to run on the system, the available installation space and the client's budgets. Our engineers designed a hybrid power system, tied to the grid and supported by battery storage, that would offset the power deficit and provide back up power to appliances up to at least 800kW.


Solar Panels

Three (3) 350W monocrystalline Era Solar were connected in a single string of three panels.


Monocrystalline panels were used in designing the system. Mono panels are the oldest and most developed of solar panel technologies. They are generally regarded as as the premium in solar panels. Learn about the different types of solar panel technologies here.


Designed with building space in mind, the solar panels were mounted on the roof. Solar panel modules require a special way of attaching them to surfaces and holding them in place. They are not weldered, soldered or hammered as they contain delicate parts that would be destroyed in the process. A solar mounting system is a metal structure or parts that are used to secure solar panels to structures. Since majority of solar panels are manufactured to be installed on rooftops, solar mounting systems are metal parts that are used to secure solar panels to rooftops in most cases. They are often an integral part of the entire solar electricity system design for retrofitting onto rooftops. More here.

Inverter

An 8kVA Growatt Inveter was used. Growatt inverters are pure sine wave hence they produce a clean electricity for appliances and appliances that use them do not make a continuous humming or buzzing sound.


The definitive feature of Growatt inverters is that they are transformerless inverters. The major difference between the conventional inverter and the transformerless inverter is that the transformer is replaced with a computerized multi-step process and other electronic components. These components play the role of the transformer, that is, convert the DC generated by the solar panels to AC. As TL inverters has no transformer, Growatt inverters are light, compact, and far relatively cheaper than conventional inverters.


Growatt inverters are sleek, compact and complement interior designs. They also come with displays that help the user interpret the state of his system and control the system.

Batteries

The system incorporates two (2) Fullriver AGM batteries. Batteries provide the DC that is to be converted to AC by the inverter for use in appliances. They also store energy produced from solar panels for later use.


AGM batteries are the safest battery design. Built to be maintenance-free for life, they eliminate worries about explosions and constant maintenance.


Voltage Regulator

A special feature of this installation is the voltage regulator. For battery-prioritizing systems, AVRs are considerations for users that use their systems on auto-mode or charge it with generating sets or depend on grid power from NEPA. It serves to help keep the input voltage at the required level. For instance, when grid power is available and is below 180V, the inverter will not internally bypass to allow charge and NEPA usage simultaneously. So as to make up for the discrepancy, the output supply will be from batteries both while NEPA is present and when it is absent. This increases the chances of the battery bank always been drained and/or overused.

Protection Features

In addition to the protection features provided by the inverter against reverse current, overload and overcharge, the system incorporates extra protection features including AC and DC circuit breakers and surge adapters. They offer additional protection to the client's investment. They also make it easy and safe to disconnect the system from the panels in the case of emergencies like lightning that could damage the inverter or solar panel fires.


SolarKobo helps its clients in Lagos and elsewhere in Nigeria make the best possible choice of all solar products including solar panels, batteries and charge controllers that meet their peculiar power needs and fits their budgets. We also have university-trained engineers who provide the best possible installation services on order.
