3 Grant Solar Technology and Cylinder Range Making a difference Renewable energy has a key role to play in reducing CO emissions and, in particular, the installation of solar technology is an effective way of reducing a building s carbon footprint. Solar technology is great for the environment, as it has no emissions and is assured for the next 4 billion years! It might also be worth noting that incorporating solar into a property is likely to increase its value. If you look at it in another way, houses with solar are only marginally affected by increasing fuel prices, therefore making them an extremely attractive option to potential buyers. Solar Thermal Solar Thermal is a clean and highly efficient means of using renewable energy from the sun to provide the hot water used in the home. The basic principle is easy to understand. If you unroll a garden hose on the ground and leave it exposed to the radiant heat of the sun, in a short time the water in the hose will become warm. Solar thermal collectors work in very much the same way, only more efficiently. Usually, but not exclusively, roof-mounted solar collectors will be connected to one of the coils of a twin-coil cylinder using a sealed circuit containing a special glycol/water solution. This fluid not only withstands the high temperatures in excess of 00 C in the collector on a summer day, but also will not freeze in temperatures down to 5 C. The pump in the system circulates the heated fluid from the panel to the cylinder where the heat is transferred to the stored water through the lower coil. The benefits of Grant Solar Thermal Installing a Grant Solar Thermal System has many advantages. Apart from reducing the amount of fossil fuels used, and the resultant savings in annual fuel bills, the reduction in harmful emissions will help minimise the long-term effects on the Earth s climate. All components within the Grant Solar Thermal Range are regularly tested under simulated real conditions to ensure customers receive a product of the highest quality and reliability. Grant Solar Thermal collectors incorporate self-cleaning glass and can be installed on sloping roofs using either an on-roof or in-roof mounting system and also on flat roofs if required. Grant Wave Cylinder and Copper Cylinder Range Solar radiation in the UK and Ireland This diagram shows the total average solar radiation falling on 1m surface, inclined at 0 to the horizontal, measured in kilowatt-hours. The average property requires approximately,000 kwh per year for domestic water heating. Technology for the future Grant Engineering has achieved an enviable reputation within the heating industry for its high efficiency approach to new concepts. The same can be said about the new range of indirect high efficiency stainless steel and copper cylinders, which are suitable for either conventional or renewable applications. The new Grant cylinders have been developed to the highest specification, as you would expect from any Grant product and have powerful mains-pressure performance, with exceptionally high hot water flow rates, whilst the copper cylinders have been specifically designed to be fitted on a well / bore hole water supply. These ranges are ideal for the typical Eco-friendly home, with a need for a reliable, energy efficient, hot water supply. Free energy! Many people believe that solar panels only work in the summer, however this type of free energy is available throughout the year. From May to September Grant Solar can produce 100% of the energy required for heating your domestic water (see right). The Grant Sahara collector operates not just with direct sunlight, but also diffused sunlight, so they even work on cloudy days. On average Grant Solar can provide up to 70% of your hot water needs per year, for free! Sunny Cloudy Hazy Overcast 1000 W/m 600 W/m 00 W/m 100 W/m (ROI) (NI)

4 Grant Solar Collector Grant Solar Overview The Grant Solar Thermal Range encompasses many unique components, including the Sahara flat plate collector, multifunctional controllers with LCD displays and various mounting arrangements, including In-Roof, On-Roof and Flat-Roof options. SAHARA Overview The Sahara Collector has a slender, extremely durable aluminium frame with a tasteful bronze finish. This blends with most roof types on domestic dwellings. Proven Reliability During the manufacturing process, the use of premium materials guarantees the collectors reliability and durability. Independent assessments verify that the panels and their components conform to the most stern European quality standards. 04 x 114 x (a1) 0.86 (n) * *Test conditions - irradiance 1000 W/m Ambient temperature 0 C. 4

5 Solar System Grant Solar Thermal can integrate easily with conventional water heating systems. Installation typically takes a couple of days to complete. The pump station incorporated in the diagram above features an air eliminator that allows the system to be both filled and purged of air in a single operation. Unlike other arrangements there is no need to install an air vent on the roof and also no need for frequent maintenance (ROI) (NI) 5

6 Grant Solar Design Ease of ordering To make life as straightforward as possible, Grant have introduced a series of individually numbered kits that meet most installation requirements. These simply consist of Sahara collectors, a roof mounting system, expansion vessel, pump station, control panel, pipe connections and solar fluid. Designing your system Grant Solar collectors have an absorber (or nett) area of.14m. As a rule of thumb, when sizing a system, you should allow m of nett collector area, per person. Cylinder requirements are litres capacity per m of nett collector area. To simplify this, for a -collector system of x.14 = 4.8m, you would require a cylinder of approximately litres. This should be sufficient for 4 people and satisfy up to 70% of your hot water demand per annum. Things to consider: Location of building Orientation of building Angle of inclination (roof) Shading of collectors Collector array in m Hot water requirements Size of cylinder Pipework requirements How to calculate the number of collectors required Direction of roof Solar radiation (see map on page 04) kwh/year South South west / South east West East Number of people per household <

7 Grant Solar Components Solar controllers The Grant GSX1 and GSD differential temperature solar controllers automatically manage the operation of the solar thermal system. Monitoring the temperature in both collector and cylinder, they operate the circulating pump only when the difference in temperature will provide efficient heating of the hot water. They will also stop the circulating pump if the temperature in the collector exceeds the maximum set or, if the cylinder has reached the required temperature. The new GSX1 controller is used for simple systems, where collectors are located on the same side of a roof - such as with a south facing installation, whereas the GSD is utilised for more complex projects, where collectors are facing the different directions, located on either the side of a roof - such as with an East/West facing installation. Both solar controllers monitor and display the amount of solar power produced by the system on a daily and cumulative basis. The controllers can display the collector and cylinder temperatures and also incorporate a pump kick facility which activates the pump for a short period each day to prevent the possibility of seizure if not operated for more than 4 hours. Expansion vessel Available in 18 and 5 litres, the expansion vessel connects to the solar pump station by a flexible hose. It incorporates a special membrane selected to withstand the higher temperatures found in solar thermal systems. Solar pump station The Grant Solar pump station has been redesigned to make it more compact. The latest version has a black cover, housing the -speed circulating pump, along with all other control components and is designed for vertical wall mounting. The flow and return ball valves incorporate temperature gauges to monitor return and flow temperatures and have integral antigravity brakes to prevent gravity circulation around the circuit when the pump is stopped. The air eliminator with manual bleed screw allows for rapid air removal from the sealed system. The 6 bar pressure relief valve is mounted on a manifold with the system pressure gauge and expansion vessel connection. Filling and flushing of the system is made easy by the combined fill and flush valve assembly and the adjustment of fluid flow rate is simple using the integral flow indicator. Solar fluid The solar fluid is an odour-free, non-toxic 40/60 propylene glycol/water solution, developed specifically for solar thermal applications to protect systems from freezing. The nitrate, phosphate and ammonia free fluid has been formulated to remain stable over long periods of time and is also a good corrosion inhibitor. It is available ready mixed in 10 or 0 litre packs (ROI) (NI) 7

8 Grant Solar Mounting Options Roof inclination and direction On-Roof When choosing a system there are a number of factors to consider. Almost any roof type is suitable, however a south facing arrangement could gain 100% of the light available during the day. If the roof was to face South-East or South-West there will be a reduction in yield by 5-10%. Positioning Collectors can be positioned on the roof either in a portrait or landscape arrangement, as shown below. Up to 5 collectors can be used in series. Portrait Grant Solar collectors can be quickly and easily located above the roof tiles or slates using brackets and a mounting rail attached directly to the roof trusses. This system is available with fixing brackets suitable for all roof tile types including slates, on roof pitches ranging from 0 to 60. The on-roof mounting system is supplied as standard with any Grant Solar Kit. In-Roof Installation of Grant Solar collectors set into the roof tiles or slates ensures a low-profile appearance. The roof surface beneath is closed within an aluminium weathering cassette incorporating flashings, drainage channels, etc. In new build applications this mounting option reduces roofing costs, as tiles are not required beneath the installation. Flat-Roof Landscape The flat-roof system is based upon the on-roof design. The mounting rails are fitted to a rigid inclined frame structure. This method allows the collectors to be positioned quickly and easily on a flat roof. 8

9 Grant Wave Cylinder and Copper Cylinder Range Exceptional efficiencies Grant DuoWave, DuoWave Plus, Copper Dual Coil and Copper Triple Coil cylinders have sizes ranging between 00 and 500 litres. These efficient appliances have been designed to be coupled with almost any household hot water system from oil and gas boilers to electric heating and solar thermal.
