Do I Need a Solar Battery Storage System?

Solar power can be generated when the sun is shining but once the sun goes down less energy is produced. If you have a solar battery system the energy generated during the daytime can be stored in the battery to power your home in the evening.

Without a battery you are using power from the Grid in the evening which increases your energy bills and carbon footprint. With a battery system installed, you can reduce your overall bills and carbon footprint thus become less reliant on the Grid.

Store energy for later use

Significantly lower your energy costs

Earn money by selling stored energy to the grid

Become independent from the grid

What and Why

What is Renewable Energy?

Renewable energy is energy that is collected from renewable sources like: sunlight, wind, rain, tides, waves and thermal heat. McNally Renewables are supporters of the “Road to Zero” initiative and have created a hassle free method of applying and installing green energy sources to your home. 

Providing home owners with options to electrify and heat their homes by minimising the overall carbon footprint, we aim to lower carbon emissions in as many ways as possible. If you already have solar panels installed at home there’s still options available to harness and utilise that energy to charge your electric vehicle or charge a battery to power your home in the evening.

Why Do I Need Renewable Energy?

Renewable energy provides a clean and reliable power supply to your home using solar panels or wind turbines. Renewable energy also helps lower grid demand and can often result in gaining rewards as you supply energy back to the grid when there’s a surge in demand.

A/C vs D/C

AC Versus DC Coupling: Pros and Cons

AC Coupled

Requires separate inverters for your battery and panels.

  • More juice: you get the combined power from battery and panel inverters
  • Flexible location. As batteries are best at room temperature and inverters are best at cooler temperatures, it’s easier to optimise both because they don’t need to be near each other
  • Battery faults won’t affect your Solar PV & vice versa
  • Works with any Solar PV system
  • 1-3% less efficient power transfer than DC
  • Sometimes more expensive as requires more than one inverter

DC Coupled

Battery and panels share the same inverter.

  • More efficient power transfer than AC by up to 3%
  • May be cheaper install as Solar & Battery share the same inverter
  • Limited access to power.
  • If there is a fault with the inverter in the future, it may render the battery useless as a compatible inverter may no longer be available.
  • Battery must be installed near the inverter. Batteries prefer temperatures around 20°C while inverters need to be in the cool, so there may be a trade off in efficiency

What Clients Say

"What a great company. McNally Electrical were recommended to me, and I can't praise them enough. From Rachel & Nicola in the office, to the guys who came to install my EV charger. If you are looking for a company to install your EV charger I can't recommend these guys highly enough. Rachel & Nicola could not have been more helpful when arranging my booking, and answering my questions pre-installation. The installation team were quick, efficient, polite and did not leave a mess. So thanks to all at McNally Electrical I certainly will be recommending you guys to anyone who needs their EV charger fitted."
