June News Flash
Batteries do not affect FIT's and Exports, Servicing Renewable Technologies, Coming Soon - CTS Tree Services
Welcome to the June 2016 News Release from CTS Renewables. This month we clear up some confusion over solar battery systems, review the benefits of servicing and maintenance and give details of our latest development.
1 - Batteries Do Not affect FIT and Export payments, I have been receiving several calls regarding how a battery system will affect payments. The battery is a temporary store of the electricity only, all solar generation goes through the solar meter sooner or later.
With DC coupled systems such as SolarEdge/Tesla, Growatt or Solax/LG the solar electricity is effectively diverted directly from the panels to be temporarily stored in the battery, when that stored electricity is required in periods of low generation it goes through the inverter, converted to AC and passes through the generation meter. What you will find is the generation meter starting to flash at night as the battery is being drawn upon.
With AC coupled systems such as the new SMA/Tesla combination, the solar electricity is immediately converted to AC by the inverter as normal and then converted back to DC for temporary storage. The battery can be fitted before or after the generation meter, and will therefore be counted either after or before usage. Either way its always accounted for!
With regards to Export payments, any systems below 30kw are are declared to be deemed export payments only, which means they are based on an assumption of 50% of the FIT generated rather than actual calculated export. Some of our customers with systems below 30kw have requested export meters to be fitted, because they know that they export more than they use, they have been refused a meter on every occasion. There is no appetite with the suppliers to bother with the effort of metering FIT payments below 30k, equally there is no requirement to notify them of storage systems such as batteries and iboosts. Export is payed as normal.
2 - Servicing Renewable Technologies - CTS Renewables customers whom have had Heat Pump, Biomass Boilers and Solar Thermal Systems fitted, will already know that we are able to provide servicing on our installed products. But, there are other newsletter subscribers which may not be aware that we can provide Servicing, maintenance and health checks for the following products and technologies whether we installed them or not. With the highlighted brands, we are manufacturer approved technicians:
Air Source Heat Pumps - (Dimplex, Samsung and Panasonic only)
Biomass Boilers - (Windhager, Okofen, Grant, MCZ only)
Solar Thermal - All sealed systems
It is essential to keep your service schedule up-to-date in order to maintain manufacturer warranties, optimise the efficiency of the units and to identify possible faults in their early stages, before the repair costs increase.
Solar PV - This service is a great option for customers who are looking to ensure that their system is achieving optimum performance for the best Feed in Tariff income.
Additionally we are aware that there has been several Solar PV companies who are no longer trading, leaving customers without equipment support or possibly poorly performing installations. As part of the health check we can identify faults and provide solutions.
3 - CTS Tree Services - For several years now my business partner, Ben Moss has been undertaking tree work as a "fun" distraction from his normal day to day work!. As often happens with side projects, the amount of interest in the service generated purely by word of mouth and recommendation, is such that we have decided to build a business around it. CTS Tree Services, is a new project which will soon be fully operational, and we intend to provide the same quality experience to our Tree Service customers as we provide to our Renewables customers. If you have any projects you wish to discuss please contact Ben in the office on 01623 422254 or visit our soon to be launched website www.ctstreeservices.co.uk
Thank you for taking the time to read our newsletter, more information on our products and services can found on our website www.ctsrenewables.co.uk or you can call our office on 01623 422254.

April News Flash - Battery Storage Special
Welcome to the April 2016 News Release from CTS Renewables Ltd. This Month we concentrate on the latest developments in Battery Storage Solutions, if you would like any additional information please ring the office on 01623 422254.
A solar PV system converts sunlight into electricity which is automatically used to charge a battery storage system and directly power a property with any excess being routed back to the grid. Any shortfall of power, such as peak use times or at night, is supplied by the battery at first then topped up by your energy supplier if the battery becomes depleted or overloaded by demand.
Solar PV operates on light intensity, not heat, so even if the day seems cold, if there is light, the system will be generating electricity, PV systems will therefore generate electricity all year round. typical usage of the energy generated is 50%, but with battery storage, usage can become 80%. We have calculated that with a typical system size of 4kw and a battery storage solution of around 6kWh, customers should be mainly off grid for spring, summer and autumn, and pretty much using all the winter generation.
Please be aware that this is not a battery backup system, but a storage system enabling more effective usage of energy generated. Battery backup systems are not compliant with UK grid systems (G83/2) and as such require additional measures to manually switch the system off the grid and also separate high usage circuits within the property.
All the solutions CTS Renewables Ltd are providing use Lithium Ion batteries rather than Lead Acid. This is because Lithium batteries are the most energy dense (power/space taken), have improved discharge cycles (usage lifespan) and have a depth of discharge of around 90% rather than 50% for lead acid (DOD is the usable proportion of the battery capacity, a 10kWh lead acid battery only provides 5kWh of usable energy!)
Due to the size and weight of the battery it stands on the ground and is secured against a wall. This means it is most suited for installation into an attached garage or similar type location.
1 - Tesla Powerwall 6.4
CTS Renewables Ltd are please to announce that we are one of the few Certified installers of the Tesla Powerwall storage solution. We feel that this is a great reflection on our commitment to quality installations as Solaredge and Tesla hand picked a limited number of companies to install this fantastic product.
Each Powerwall has a 6.4 kWh energy storage capacity, sufficient to power most homes during the evening using electricity generated by solar panels during the day. Multiple batteries may be installed together for homes with greater energy needs. Powerwall stores electricity generated by solar panels during the day and makes it available to your home in the evening. This bridges the gap between peak solar and peak demand, allowing you to use your photons when you need them, potentially becoming "net zero". A net zero energy rating means that your home produces as much energy as it consumes, but is still connected to the utility grid for periods of high demand.
Specs - 6.4kWh of storage at 100% depth of discharge, up to 3.3kw discharge power, rated for internal and external mounting, 1302 mm x 862 mm x 183 mm / 97kg. 10 year product warranty. https://www.teslamotors.com/en_GB/powerwall
Currently the Tesla Powerwall is only compatible with recent model SolarEdge Inverters. Other Battery Systems are available or it is possible to upgrade your existing system to Solaredge for an additional charge.
To add a Tesla Powerwall onto an existing SolarEdge system would be from £4,499,
To install a new system with 4kw Canadian Solar Panels, Solaredge and Tesla would be from £9,599
2 - SolaX SK-SU3700e Solar Battery Inverter with LG Chem Resu 6.4EX Lithium 5.76kWh Battery Module
For customers without Solaredge Inverters already installed we have put together an alternative but equally attractive battery storage solution. In this package the existing inverter is replaced as it is more cost effective and efficient to replace with a Hybrid inverter such as the SolaX as it is to add a dedicated battery inverter onto an existing system. We have paired it with a quality Battery module made by LG Chem.
The ground-breaking SolaX X-Hybrid is much more than just an inverter. It is an intelligent, integrated system that manages the energy you generate effectively and efficiently.
