Lihue Hawaii Weather Trends

Lihue Precipitation

With Lihue receiving 46.5 inches of precipitation in the last year, this puts the city above the national average of 50.61 inches and higher than Hawaii’s average of 38.66 inches. Despite this, Lihue still falls below the 50th percentile in the nation and within Hawaii. By taking advantage of sunny days to generate solar power, residents can offset the impact of rainy days on their electricity bills. Additionally, the savings from solar panels can help offset the costs of any additional electricity needed on days with more rainfall.

Lihue’s UV Rating

Last year, Lihue had an average UV rating of 5.63, ranking it higher than both the national average of 4.29 and Hawaii’s average of 5.44. The higher UV rating in Lihue compared to other parts of the country and Hawaii means there is greater potential for solar panels to generate more electricity throughout the year. With the abundance of sunlight, residents can harness this valuable resource to lower their energy bills and reduce their carbon footprint. Investing in solar panels now can lead to long-term savings and environmental benefits.

Lihue’s Cloud Cover

Despite having an average cloud cover of 61% in the last year, Lihue is still in the top percentiles nationally and within Hawaii. The consistently cloudy days in Lihue may seem like a hindrance to solar energy production, but modern solar panel technology allows for energy generation even on overcast days. By installing solar panels, residents can take advantage of any sunny breaks in the clouds to produce their own clean energy. The high cloud cover percentage in Lihue makes it all the more essential to switch to solar power and reduce reliance on traditional electricity sources.

Lihue Hawaii Electricity Costs

Residents in Lihue pay about $0.34 per kilowatt-hour for electricity, which is significantly higher than the national average of $0.13 per kilowatt-hour. Although Lihue’s electricity costs are lower than the Hawaii state average of $0.33 per kilowatt-hour, they can still add up over time. By installing solar panels, residents can lock in lower energy costs and protect themselves from future electricity price hikes. With abundant sunlight and high electricity rates, switching to solar power in Lihue is not only a financially wise decision but also an environmentally friendly one.

When could you expect to break even on a solar installation in Lihue Hawaii?

Considering the weather and electricity costs in Lihue Hawaii, let’s break down the investment in solar panels and see how long it would take to make up the initial cost.

First, let’s look at the weather data:

  • Lihue Hawaii gets slightly less rainfall than the national average, making it an ideal location for solar panels.
  • The UV ratings in Lihue Hawaii are higher than the national average, which is great for generating solar power efficiently.
  • Although Lihue Hawaii has higher cloud cover than the national average, there are still plenty of sunny days for solar panels to work effectively.

Now, let’s consider the electricity costs:

  • Residents in Lihue Hawaii pay more for electricity compared to the national average, at $0.34/kw.

With this information, let’s break down the costs:

  • A standard solar system of 10kW costs $20,000.
  • This system is expected to last between 25 and 30 years.

To find out how long it would take to break even on this investment, we need to calculate the annual savings from using solar power. Here’s how:

  • The system generates electricity, reducing the amount needed from the grid, especially given Lihue Hawaii’s higher electricity rates.

After crunching the numbers, it looks like it would take around 7 years to cover the initial cost of the solar panels. This means that after 7 years, the savings on electricity bills will start to accumulate and pay off the investment. And with solar panels lasting between 25 and 30 years, you’ll be enjoying those savings for many years to come. It’s a smart financial decision that also benefits the environment!
