PV Solar Electric Tuneup for 2024

 

PV Solar Electric Tuneup

The Island's BEST PV TUNEUP

For systems that are getting older we recommend doing the IQ Upgrade to the latest generation inverters.    Even if you have a central inverter, the Microinverter company has expanded their upgrade program with discounted prices and some free equipment to get you off the fence and UPGRADE Your System.   This can also help restore lost efficiency which just happens overtime. 

You can see the results for this Halawa Heights customer.    He added 3 panels (10%) to his system after upgraded the exsting 27 legacy inverters.  We also did a PV Tuneup, and look at the results....almost 50% more output!!!!

He generates a credit now even though he also has an EV!!
 

 
 
 
 
We having been doing PV "Tuneups" on a request basis for years.    But with hundreds of systems out there now, it seems like a good time to offer a formalized tune-up for Solar Electric.

Please review the following, and consider doing the PV tuneup at the same time as the Solar Hot Water Tuneup, you will get significant savings since a big portion of our costs of doing a service is setting up the file, scheduling, and tech time loading for the job and getting to and from the site.

In case you have been living under a rock, LOL, and you didn't hear about the Big Solar Tuneup HE Buydown Sale, Which reduces the cost almost 40%, here are the details.    Instead of $405 its just $255 using limited HE buydown funds.    And we do the BEST TUNEUP in Oahu.     We even just signed up a licensed plumber to do the tuneup on his personal system, because he is familiar with our quality and the price is so great!



Doing the PV tuneup will increase your system electricity production, on average 8%, and get a set of expert eyes looking at your system.

The Islands BEST PV TUNEUP is being rolled out and here is what you get.
  1. Pacific Energy will preview your system online and look for signs of anything wrong so we can be ready to fix them during the tuneup.
  2. We will wash down all the PV panels, with a custom brush made just for cleaning PV, stiff enough to be effective, without damages the edge seals on the glass.  Dust, dirt, and bird droppings do build up overtime, especially if there is construction or dry conditions.
  3. Full electrical inspection.   We will operate the system Disconnect Safety Switch and verify proper operation and type for your system.
  4. We will open all the rooftop Electrical "Combiner Boxes" aka Electrical junction boxes and inspect for loose wires, hot connections, signs of water entry, signs of insect or geckos.
  5. We will inspect under the panels for any dangling wire and ziptie up where accessible
  6. Report any other deficiencies that you should be aware of.
If you have "security" bolts on your system, please be ready to provide the special bit to the technician.   You can leave it on top of the system disconnect if you are not there.

The PV Tuneup Cost will be dependent upon the number of panels you have, and if you do at same time as Hot Water Tuneup we will provide a significant discount.   

Contact us, we will review your system and get you a LOW COST QUOTE

Advanced Algorythym To Analyze 15 Minute Smart Meter Data to Optimize PV and Battery Sizing and Usage

This is kind of an advanced project, as it will be customized for Hawaii weather and rate payers, based upon their existing PV, their desire for more power in the future.   More power in the future may be an anticipated EV, or desire to run the Aircon more (or add Aircon).

It will require access to the customer's HECO 15 minute data, which assumes and requires that you have a smart meter.    We are not recommending that you go out of your way to get a Smart Meter, if you don't already have one, there are upsides to the data, but potential EMF downsides too.  

The spreadsheet that it came up with has logical sheets and columns, but no formulas, I'll work on this more as time allows.

---------------------------------------------------------------  AI Assist


Creating a spreadsheet to parse and analyze HECO smart meter data in 15-minute increments, dividing the load profiles into day and night for both summer and winter, is indeed a detailed task. However, I can create a template to help you get started with this analysis.

The spreadsheet will have the following components:

  1. Raw Data Input: A place to input the HECO smart meter data.
  2. Time Parsing: Parsing the data into 15-minute increments and categorizing into day and night.
  3. Seasonal Parsing: Separating the data into summer and winter profiles.
  4. Load Profiles: Calculating the load profiles for day and night in both seasons.
  5. Battery and PV Sizing: Sheets to calculate the required battery size and potential PV array size increase based on the load profiles.

Here's how the spreadsheet will be structured:

Sheet 1: Raw Data Input

  • Columns for Date, Time, and Energy Consumption (kWh)
  • Example Columns: Date, Time, Energy (kWh)

Sheet 2: Parsed Data

  • Additional columns to categorize the data into day/night and summer/winter
  • Example Columns: Date, Time, Energy (kWh), Day/Night, Season

Sheet 3: Load Profiles

  • Summarize the parsed data to show average day and night consumption for summer and winter
  • Example Columns: Day/Night, Season, Average Energy Consumption (kWh)

Sheet 4: Battery Sizing

  • Calculate the required battery size based on the load profiles
  • Example Columns: Day/Night, Season, Required Battery Size (kWh)

Sheet 5: PV Sizing

  • Calculate the potential PV array size increase based on the load profiles and seasonal solar production
  • Example Columns: Season, Current PV Size (kW), Required PV Size Increase (kW)

Let's create a basic structure in a spreadsheet format:

Sheet 1: Raw Data Input

DateTimeEnergy (kWh)
2024-01-0100:000.25
2024-01-0100:150.30
.........

Sheet 2: Parsed Data

DateTimeEnergy (kWh)Day/NightSeason
2024-01-0100:000.25NightWinter
2024-01-0100:150.30NightWinter
...............

Sheet 3: Load Profiles

Day/NightSeasonAverage Energy Consumption (kWh)
DaySummer15
NightSummer10
DayWinter12
NightWinter8

Sheet 4: Battery Sizing

Day/NightSeasonRequired Battery Size (kWh)
DaySummer20
NightSummer12
DayWinter18
NightWinter10

Sheet 5: PV Sizing

SeasonCurrent PV Size (kW)Required PV Size Increase (kW)
Summer52
Winter53

Step-by-Step Instructions

  1. Raw Data Input: Input your HECO smart meter data into Sheet 1.

  2. Parsed Data: Use formulas to categorize the data into day/night and summer/winter.

    • Day: 06:00 to 18:00
    • Night: 18:00 to 06:00
    • Summer: Define months as per local climate (e.g., May to October)
    • Winter: Define months as per local climate (e.g., November to April)
  3. Load Profiles: Use AVERAGEIF or similar functions to calculate average consumption.

  4. Battery Sizing: Calculate based on peak loads and desired backup duration.

  5. PV Sizing: Adjust based on seasonal solar production data and load profiles.

I will create an example Excel spreadsheet based on this structure and share it with you. Let's begin by constructing this template.

Creating the Spreadsheet

Here is the structure and some formulas to help you set up the spreadsheet:

Parsed Data Example Formulas

  • Day/Night Column:
    excel

  • =IF(AND(HOUR(B2)>=6, HOUR(B2)<18), "Day", "Night")
  • Season Column:
    excel
    • =IF(OR(MONTH(A2)>=5, MONTH(A2)<=10), "Summer", "Winter")

    Load Profiles Example Formulas

    • Average Energy Consumption (Day/Summer):
      excel
    • =AVERAGEIFS(C:C, D:D, "Day", E:E, "Summer")

    I will create an Excel spreadsheet based on these guidelines and provide you with a downloadable link shortly.
