Variable Speed Pool Pumps = Huge Savings

Going solar isn’t the only thing you can do to reduce your electric bills and your environmental footprint. In fact, the first thing you should consider is how you could make your home more efficient BEFORE investing in solar. Investing in a solar system that is bigger than you really need is just a bad investment strategy since efficiency upgrades are often much more affordable than the solar system required to offset the ineficient loads. 

Pool with SolarOne option is to hire a professional to give you a thorough energy audit which will help to pinpoint where your electrical hogs are and what you can do to improve efficiencies. Alternatively, there are a lot of relatively simple steps you can take if you know what to look for. Changing out your old light bulbs to LEDs is an obvious and easy fix for example. But one of the biggest and often under the radar culprits that I’m here to tell you all about are pool pumps.

Pool pumps can have such a big effect on your electric bill that we always discuss it when doing a solar site evaluation at any home fortunate enough to have a pool. Of course we don’t recommend eliminating your pump altogether as they are necessary to keep your water filtered and clean. So what is the solution? There are all sorts of newer “efficient” pool pumps out there and likely your pool guy/girl will happily install if you say you’d like an upgrade. However, what you really need if you want to make a dent in your electrical load is something called a “variable speed” pool pump.

A variable speed pool pump is exactly what it sounds like… Rather than pumping water with a consistently high speed you really only need max power at the outset to get the water moving. Once its moving the variable speed pump then downgrades the output power to keep the water moving since less energy is required to keep something moving than to get something going from a standstill. This reduced speed equals reduced energy loads! 

We have heard clients who installed variable speed pumps have seen reductions on their bill on the order of over $500 per year!

The downside for these pumps is often the price is much higher than regular pumps. But I come bearing good news! Many utilities offer rebates and incentives for Energy Star qualified pool pumps. In our home turf of Pasadena, California we are fortunate to have a very proactive utility, Pasadena Water and Power, striving to help residents lower their footprint. They normally offer a rebate of $400-$450 off the sticker price for a variable speed pump. However, I was just notified that PWP is running a promotion on all of their energy efficient appliance rebates through October 31st, 2016: 

“PWP is offering a $900 (bought outside Pasadena) to $950 (bought locally) rebate to all PWP residential electric customers who replace their old pool pump with a new energy efficient variable speed or variable flow pool pump and motor. Replacing older inefficient pool pumps with new efficient models will not only help you reduce energy use but save you money. With the summer heat and the possibility of rolling blackouts, PWP wants to make sure you do your part to conserve energy." 

We couldn’t agree more! Check PWP’s rebates listing for a list of other rebates to take advantage of. The listed prices on the website include the current promotion. 

If you’re not in PWP’s service area, never fear! You can check if your utility has rebates on the Energy Star website

After you’ve addressed all the drafty windows, switched out your lightbulbs and upgraded all your appliances, then it is time to give Run on Sun a call (626-793-6025) and we’ll help you offset the rest of your energy needs!

Solar Plane Crossing the Atlantic! - UPDATED!

UPDATE - 6/23/2016 - SI 2 has arrived safely in Seville, Spain, and did so in just 71 hours, 8 minutes (of the planned 90-hour duration).  Read more on the SI2 blog page.


Solar Impulse 2- that amazing solar-only powered aircraft - is in the air again, this time undertaking a predicted 90-hour flight from New York City’s JFK airport to Seville airport in Spain!

You can see how its systems are performing - solar cells charging the plane’s batteries and powering its ascent during the day, and the batteries propelling the plane during the night as it descends - by following the very cool charts embedded below.  (You can read some of our earlier coverage of Solar Impulse 2 here.)

Happy Birthday Pasadena... and Run on Sun!

Everyone knows that when it comes to Pasadena, Run on Sun is the premier installer of solar PV systems for residential, commercial, and non-profit clients (if you doubt it, just ask us!).  But we have one other cool thing in common - we are both marking milestone birthdays this year!

Happy Birthday, Pasadena!

While our hometown is turning 130, Run on Sun is turning 10 years old this year!  (Which, if you think about it, is nearly 130 in solar-installer years!)  So when we heard that the folks at Pasadena Weekly were looking to feature ads that wished the City a Happy Birthday, we just had to get into the act!  (If you are in the Pasadena area, you will find the ad - with art work by that Solar Kid Julia who will soon be a college sophomore - on page 42.)

Happy Birthday to us both, and many happy returns!

Top 3 Ways Solar = Water Conservation

After 4 years of severe drought and this year’s winter snowpack at a pathetic 8% of typical levels, it’s obvious that California will have to find real solutions as populations rise and the effects of climate change worsen. We rely on the High Sierras’ snowmelt throughout the year for everything from our green lawns and fresh food (throughout the US) to our hydroelectric power.

Governor Jerry Brown’s recent mandate for cutting water use by 25 percent was overdue and necessary, but communities will have to step up conservation efforts in a big way. Ever since the Governor’s big announcement ideas for how best to curb water use have been flowing. So why should PV solar power generation be at the top of the list? What does water conservation have to do with solar?

    1. As noted previously in “Thirsty? Think Solar!“… compared to other energy sources, photovolataic solar energy systems have the lowest life cycle water use.  Increasing the amount of electricity generated by PV directly reduces our water demand
    2. Once a big player in California energy production, hydropower dropped from 12 percent in 2013 to just 6 percent in 2014 due to the extreme drought conditions. But solar has stepped in to fill that gap, with production more than doubling to provide 5 percent of California’s power in 2014—and that figure doesn’t even count rooftop solar! According to the Energy Information Administration, solar PV and concentrating solar power together offset 83 percent of the total hydropower decline.
    3. With drought comes a severe shortage of rainy days. Anyone with solar panels knows the joys of monitoring your energy output on a sunny day and the much sadder numbers that result on a gray day. As the drought persists, California’s sunshine provides an endless resource that should be tapped.

Solar is an increasingly important solution to water scarcity as well as energy security. With no sign of a solar slowdown in California—we are the first state to get 5% of its energy from solar—strong generation records are likely in coming years. While solar has been included in some communities’ plans to reduce water use (such as in the Los Angeles “pLAn“), many people are unaware of this solution. Communities, individuals and businesses installing rooftop solar can make a real positive difference for California’s dire water situation.

Solar Impulse Launches Zero-Fuel Flight Around the World

http://info.solarimpulse.com/uploads/thumbs/860x576/2015_02_26_Solar_Impulse_2_RTW_First_Test_Flight_AbuDhabi_Revillard__09.jpgSolar Impulse is the first airplane to fly day and night on solar power alone. To be clear folks, that means 22,000 miles without a single drop of fuel.

Run on Sun has been following the exciting developments of Solar Impulse since it’s prototype began its groundbreaking test flight across America in 2013.

After the lessons learned from the American flight, an upgraded Solar Impulse 2 was developed with a wingspan wider than a Boeing 747, more than 17,000 solar cells and 1,300 pounds of batteries. Amazingly, the aircraft still weighs no more than an average car!

Finally, this  morning, on March 9th, 2015, Solar Impulse 2 and her team were ready to embark on their record-breaking aeronautical journey around the world. The first leg officially departed from Abu Dhabi at 7:12AM UTC+4. Landing in Muscat, Oman at 20:13PM UC+4 pilots Bertrand Piccard and Andre Borschberg rested for a few hours before continuing onward to Ahmedabad, India.

With a top speed of 50 mph, the entire circuit is planned to take four or five months before returning safely back to Abu Dhabi. You can follow their flight online as well as chat with the mission control center and view cockpit measurements like solar battery storage and pilot heart rate!

Solar Impulse is not only about accomplishing the first round-the-world solar flight. Behind the development of this technological feat lies a very powerful message. Piccard and Borschberg are using each landing as an opportunity to reach out to governments, NGOs, education centers, and the broader public to share what is possible with clean technologies.

“We shouldn’t be listing targets, but rather solutions – ways of meeting those targets. Because these solutions exist. Our society could already cut energy consumption in half by replacing old, outdated, polluting technology with clean technologies. Couldn’t we, all together, persuade governments to modify the legal framework so as to encourage the replacement of polluting technologies by cleantechs? That would at least make debates constructive and international climate conferences interesting.” - Bertrand Piccard

In conjunction with Solar Impulse’s round-the-world flight, the pilots started an online campaign called “Future is Clean”. In December 2015, they will share the largest collective voice in favor of clean technologies with global leaders at COP21, the United Nations Climate Change Conference in Paris. You can add your pledge and share with your networks at www.futureisclean.org.
