Heliostat

What’s a Heliostat?
An apparatus containing a movable or driven mirror, used to reflect sunlight in a fixed direction.    As the sun moves across the sky, a heliostat makes small adjustments to the position of a mirror in order to keep reflected light on a target.   The larger the mirror mounted on the heliostat, the more energy and light is delivered to the target.  Multiple heliostats can reflect light onto the same target to deliver large amounts of heat and light.
What Can I do with a Heliostat?
Heliostats are the most efficient and low-cost way to harness solar energy.  The uses for heliostats include:
  • heating homes, offices, and other buildings – one H1 heliostat can deliver over 1000 watts of heat, with no energy bill.
  • providing sunlight to shaded spaces – ‘daylighting’.  Rooms in some buildings always face away from the sun.  One H1 heliostat delivers over 230,000 lumens of beautiful natural light, free.
  • replacing fossil fuel heat in industrial processes – for example, in our solar rotational molding systems, LightManufacturing replaces expensive, polluting gas-fired ovens with an array of silent, clean heliostats.   Ask us how free solar thermal energy can transform your industry.
  • Keeping trees and plants alive and healthy in atria and courtyards or other shaded areas.
  • generating steam / ‘process heat’ for industrial applications
  • enhancing oil extraction
  • reducing the moisture content of crops – eg drying nuts prior to roasting, drying seafood
  • industrial-scale cooking
  • sterilization of medical equipment
  • melting snow and ice
  • electricity generation in ‘power-tower’ applications …and much more.

Where Can I Buy the H1 Heliostat?
The H1 Heliostat is available for sale at our heliostat order page ( click here ). The H1 heliostat is available for sale to the general public in several configurations, and we also offer sales programs for commercial customers with volume purchasing needs.
What Makes the H1 Heliostat Special?
The LightManufacturing H1 heliostat is an industrial-grade heliostat that combines robust performance with easy setup and operation – and at the lowest price per reflected watt of any heliostat on the market.   Simply put, it costs less to heat a target with the H1 that with any other solution.
What are the Wind Ratings of the H1 Heliostat?
  • steady wind / normal operation OK to 25 MPH / 11 meters-second
  • gust rating any position OK to 60 MPH / 27 meters-second
  • gust rating ‘safe position’ OK to 95 MPH / 43 meters-second
Do LightManufacturing Heliostats Require a Computer for Tracking?
No.  The H1 heliostat has an internal microprocessor, and no external computer is needed for regular heliostat operation.  A computer or smart-phone browser IS used for initial setup – eg entering heliostat location (lat/long) time of day, time zone, etc – and for defining the heliostat ‘targets’ – where you want the light and heat from the heliostat to go.   After this initial setup, which is done wirelessly, the heliostat operates totally autonomously.  All it needs is 12V DC power – which can be provided by our optional P1 or P2 solar power supplies if you’re installing the heliostat somewhere without available local power. Autonomous heliostat operation is very important if you’re managing multiple units – you don’t want your entire heliostat array taken offline because of a central computer failure, or because of a wiring problem.  LightManufacturing H1 heliostats are robust and failure-resistant in part because each one operates autonomously.   This is important both for heliostat architectural / green building applications and for heliostat solar thermal manufacturing.
Can Heliostats Generate LEED Points for my Green Building Project?
Yes.  In fact, heliostats like the LightManufacturing H1 are one of the simplest ways to add sustainable, low-cost solar heat and light to a new green building project, infill project, or retrofit.  Heliostats are low cost, and supply heat and light through existing building windows. » Read more about heliostats for LEED / green building applications.
Can I Heat a Home or Office with Heliostats?
Yes. Heliostats are a low cost way to capture light and heat and direct it into a building through windows. In many buildings, some rooms never get direct sunlight at all – they face the wrong way. Heliostats placed outside these cold /dark rooms can direct warmth and light into the rooms, transforming them into enjoyable, comfortable spaces. Each H1 Heliostat can deliver over 1000 watts to a room, or over 115,000 lumens of light. Multiple H1s can be combined to warm a single room faster, or you can use several H1 heliostats to warm different spaces simultaneously. Applications include schools, office buildings, homes, industrial workspaces, farm buildings, and many other architectural uses.
I Read About a Less Expensive Heliostat. Is the H1 a Better Investment?
The LightManufacturing H1 heliostat is a powerful commercial-grade heliostat, with a number of advantages over ‘home heliostat’ systems.
  • The H1 heliostat uses safe, aluminum composite mirrors which are shatterproof and tough, not glass like other heliostats.  The H1 mirrors shrug off impact.
  • The H1 heliostat uses only aircraft-grade aluminum structural elements for maximum durability, not plastic like other heliostats.
  • The H1 heliostat can be aimed exactly using your web browser, unlike other heliostats which require you to hand-aim the mirrors at a target.
  • The H1 heliostat can change target easily between multiple targets you define, unlike other heliostats.
  • The H1 heliostat is MUCH larger and captures more light and heat than small ‘home heliostats’.  A H1 with 4′ square mirror has a mirror area of1.5 square meters, as compared to consumer heliostats with mirrors only 0.5 square meters or less.
  • The H1 costs less per watt/lumen than any other heliostat on the market.  Purchase price of the H1 may be higher, but when you calculate the cost / square meter of mirror you’ll quickly see the advantage of the H1.
  • You can combine multiple H1 heliostats to deliver unlimited heat/light to targets you define, and you can switch all of your H1s from target to target with a single command.
How Much Energy does the H1 Heliostat Capture?
The standard H1 heliostat ships with a 1.21M x 1.21M (48″ square) aluminum composite reflector. 
  • The 48″ square mirror reflects over 1000 watts onto a target in optimal conditions, or over 115,000 lumens if used for lighting applications.   This is the most energy/light captured by a commercially available heliostat.
In contrast to the H1, some smaller / consumer-oriented heliostats offer a mirror only .5 square meters in area, reflecting @ 425 watts of energy.  It would take 4 or 5 of these small units to equal one H1 heliostat.
Do you make Solar Furnace / Solar Oven Systems?
LightManufacturing H1 Heliostats are ideal for solar furnace, solar oven, and similar applications.  Each H1 heliostat captures up to 2000 watts of solar heat, and directs it to a cooker, water heater, roasting enclosure, or other solar oven/furnace design.  Multiple H1 heliostats can target the same enclosure to deliver very large amounts of heat. Depending on your application, LightManufacturing  can supply ISO shipping container based sun furnace target enclosures, or you may construct your own target from locally available materials. Similar terms:  sun furnace, solar furnace, solar oven, sun oven. Note:  Solar Rotational Molding is covered by our several US and international patents. SRM systems are available for sale, and the technology may be licensed to qualified partners.
Can Heliostats Enhance Flat Plate Thermal Collectors?
Yes – if you have a flat plate thermal collector (for example, for making hot water or hot air) the LightManufacturing H1 heliostats can help.  Fixed position flat plate collectors typically do not work well in the morning or later afternoon, because they are installed in a ‘best average’ position to maximize mid-day solar absorption.    This means less hot water or hot air at non-peak times. Solution:  Use h1 heliostats to direct solar energy to your flat plate collector at off-peak times. However- in many cases the additional cost of adding a heliostat to a fixed flat-plate collector may not make sense.  Each case is different.
