Linear Actuator

Linear actuators are an amalgamation of several different core technologies that are incorporated in a single product.  That’s part of the reason that they are so confusing. The categories of core technologies are motive power, means of transmission, bearing technology, support and feedback.  Not all are always present.  Feedback and support may not be needed if you are doing a hydraulic system that simply opens and closes.

Motive power means electric, pneumatic or hydraulic.  Transmission means how is the power transferred to the load.  In pneumatic and hydraulic systems, there is no means of transmission, because the cylinder and piston actuator that allows pneumatic and hydraulic to operate, is the means of transmission and the bearing system at the same time.  Then there are belt driven designs, lead screw designs, and more recently linear motor designs based on electric motors for input power and control.  But there are also pneumatic and hydraulic systems that do the same things.  So navigating the technology decision is very difficult.

But once in a while, something really different comes along.  Solid Tech has a new solution that minimizes inertia mass, physical mass and system footprint to achieve payload to weight ratios approaching 1 to 1.  Accuracy and power handling capability are parameters of design that can be manipulated for any given application.  The US Patent Office has issued a patent so the technology is available for use.  Check it out.

Solar Tracking Photovoltaic Panels

Filed under: Technology Development — Tags: , , , , — smeyer @ 4:33 pm

Solar Power as an industry has been growing in huge leaps around the world in recent years. Although the rate is slowing, it is still forecast to grow in the US at 25-28% next year. Much of the growth is subsidized by government through cash rebates at the state level and federal tax rebates at the national level.  This is because solar power has a payback period of about 8 years for many applications, which means that small commercial and residential systems are too expensive to be practical.

What happens when the subsidies run out?  The risk is that if the industry does not achieve substantially lower cost and better return on investment, that the industry could stall.  Present solar panels that convert sunlight to electric power are based on expensive silicon similar to the material used to create integrated circuits.  But other photovoltaic chemistries exist and many different technologies are being developed that will bring costs down over the next few years.  So the overall outlook is still very promising.

But the single technology that has the most immediate impact on solar energy harvesting is tracking the sun.  This means moving the panels so that the sun’s light is always perpendicular to the panel.  The National Renewable Energy Laboratories say that solar tracking will increase power up to 36%.  And that is a bigger improvement than any of the advanced solar R&D programs can deliver.  And the improvement is available right NOW!

By applying tracking to system engineering, solar system costs can be reduced substantially.  The 36% increase in harvesting can be used to reduce the number of solar panels required by 36%, and that means means cutting the ROI down from 8 years to 5 years.  Further system efficiency gains through the use of micro inverters will help bring the cost and ROI into the realm that will make solar power practical for many home owners and small businesses.  And proposed legislation that will make financing solar equipment part of conventional home financing loans is in the works.

Solid Tech Inc. has unique expertise in the field of motion control and has Patents pending on a series of single panel tracking solutions that are cost effective and rugged enough for flat roof commercial and residential requirements.  We are seeking partners to help fund a very quick engineering program that will bring low cost tracking to the market in 6 to 9 months.
